An improved transfer learning method for rotor unbalance position identification from simulated data to experimental data

In the study of dynamic balancing for flexible rotors operating at high speeds, determining the unbalanced position of the rotor has consistently posed significant challenges. Accurate identification of the unbalanced position enables low-speed dynamic balancing to serve as a viable alternative to high-speed methods, ultimately reducing costs and enhancing operational efficiency. Although deep learning techniques utilizing limited labeled data have shown promising results in identifying unbalanced positions, the challenge of gathering a sufficient amount of labeled data for effectively training diagnostic models remains substantial. To address this issue, we propose a Pre-Adaptive Transfer Learning (PATL) approach that employs sample reconstruction through frequency domain correlation analysis. This technique facilitates cross-domain deep transfer recognition of rotor unbalanced positions by transferring insights from simulated dynamic model data to experimental datasets. Compared to existing methodologies, the proposed approach demonstrates significant improvements in both the accuracy and generalization of unbalanced position identification. The novelty of this research lies in the introduction of pre-adaptive transfer learning, which effectively minimizes the disparity between experimental and simulation data, thereby enhancing the model's recognition capabilities. Experimental results indicate that the proposed method achieves effective balancing outcomes across various operating conditions.

Dynamics and stability analysis of unbalance responses in mid‐positioned electrically assisted turbocharger rotor

AbstractElectrically assisted turbochargers (EAT) improve intake efficiency by motor‐assisted compressor impeller rotation, enhancing the system's transient response. However, the addition of motor rotor components has increased the number of unbalanced positions in the shaft system, leading to problems such as excessive compressor end vibration and complex changes in oil film stability. To evaluate the effects of unbalance in the motor rotor, along with the parameters of floating ring bearings (FRB), on the dynamic response of EAT, a finite element model of an EAT rotor supported by nonlinear FRB is developed, and the vibration response of the compressor end bearing is obtained by numerical integration. The results indicate: (1) In contrast to the effect of compressor and turbine unbalance, proper motor rotor unbalance is more effective in suppressing oil whirl instability in the high‐speed operating range. However, a new inner oil film whirl “instability interval” is also induced in the low‐speed operating range, leading to an increase in the Y1 compressor‐end amplitude at low and medium speeds, and this “instability interval” increases with the amount of unbalance. (2) When an oil whirl occurs in the oil film, the maximum eccentricity of the bearing surges and is greater than 0.3, which can be used as an effective threshold for determining whether the oil film is unstable in engineering applications. (3) A suitable outer oil‐film clearance range should be , otherwise, a wide range of outer oil‐film whirl instability occurs. Controlling the amount of unbalance and oil‐film clearance to suppress the sub‐synchronous vibration of the EAT, provides a theoretical basis for the design of the dynamics of the nonlinear rotor bearing system and improves the stability of the turbocharger's operation.

Grid current quality improvement for solid state transformer with an improved current controller

In this paper, the Solid-State Transformer (SST) is performed by integrating an improved harmonic compensator at the Modular Multilevel Converter (MMC) current controller in order to ensure grid current quality regardless the non-linear load or the unbalance position at the SST stages. The proposed MMC current controller is composed of a high-order harmonic compensator based on a fuzzy logic controller, giving the controller an active filtering feature, a low-order harmonic compensator, and a negative sequence harmonic compensator for unbalanced control. This makes the proposed solution a good alternative for solutions based on extra filters or increase switching frequency. Ensuring power quality independent of loads or unbalanced position in the SST while maintaining reduced switching frequency is the main focus. With the proposed current controller, both low order and high order harmonics are effectively attenuated, thereby consistently reducing the total harmonic distortion (THD) of grid current to levels complying with the IEEE-1547 standard, even when non-linear loads are placed at the LV and at the MV stage of the SST. In addition, the controller eliminates negative-sequence harmonics associated with unbalanced loads in the SST, thus preserving the balance of the grid current. Various results of the proposed current controller are presented.

Model verification and vibration analysis of the four-disk hollow flexible shaft rotor system

Rotor unbalances failure due to various factors such as manufacturing defects, mounting errors, and material inhomogeneity is inevitable, and will be aggravated by bearing pulse displacement excitation caused by maneuvering flight. Therefore, the purpose of this paper is to study the vibration of the rotor system under disk unbalance forces and bearing pulse displacement excitation. Firstly, the differential equation of motion for four-disk flexible hollow shaft rotor system modeling with a simple finite element model(SFEM) is established by the Lagrangian method in non-inertial systems, and the shaft is modeled using Timoshenko beam theory. Then, the dynamic characteristics of the four-disk flexible hollow shaft rotor are analyzed and compared with the 3D finite element model(3D FEM) to verify the accuracy of the model. To analyze the effects of different disk unbalanced positions and pulse displacement excitation on the vibration characteristics of the rotor, the characteristic vector method and the Runge–Kutta method are used to obtain the steady-state solution and the transient solution, respectively. In addition, the simulation results show that suitable in-shaft damping has a stable effect on the rotor during the start-up. Disk2 and Disk3 are more sensitive to synchronous harmonic excitation and pulse displacement excitation than Disk1 and Disk4. The research of this paper provides an important basis for vibration monitoring and control, and vibration transmission analysis of aero-engine rotor system.

Flexible rotor unbalance fault location method based on transfer learning from simulation to experiment data

In the study of the high-speed dynamic balance of flexible rotors, rotor unbalance positioning is a challenging topic. Particularly for slender rotors, the axial position of the unbalance has an important influence on the high-speed dynamic balance. The unbalance at different axial positions is not the same or even opposite in different rotor mode vibration behaviors. If the unbalance position of a rotor can be identified, the actual unbalance of the rotor can be reduced from the root. This balance method has the same effect in each vibration mode of the rotor; hence, low-speed dynamic balance can be realized to replace high-speed dynamic balance, considerably saving on costs. Deep learning based on few labeled samples can achieve good results for the identification of unbalanced positions; however, there are infinite potential positions of unbalance in the actual rotor. It is difficult to collect sufficient labeled samples to train a reliable intelligent diagnostic model. Fortunately, a large number of rotor vibration datasets labeled with different unbalance positions are available using the rotor dynamic model, and the unbalance position data calculated using the dynamic model contain diagnostic knowledge related to the rotor unbalance position data measured in the rig. Hence, inspired by transfer learning, this study proposed a transfer learning method using dynamic model simulation and experiment data for flexible rotor unbalance fault location. Cross-domain deep transfer recognition of rotor unbalance position was realized.

Are China's HSR tariff affordable and economic equitable? An international comparison perspective

While the issues of high-speed rail (HSR) tariff and its impact on equity have always been a hot topic in China, which also attracted the attention of international researchers, research on the level of HSR tariff from the perspective of individual affordability and equity issue have scarcely been considered. This study therefore aims to fill the research gap by quantifying the HSR relative tariff level and its impact on income/regional distribution via introducing a HSR affordability index.Based on the index, we calculate the HSR affordability levels of the main international sample countries with the order of magnitude. Then we expand the analysis of HSR affordability level according to differentiated HSR pricing practice in the selected countries. At the same time, we compare the HSR tariff impact on economic equity among different countries, regions, and social classes.The result indicates that although the absolute level of HSR tariff is low, China is generally in the middle/the lowest and unbalanced position among the sample countries on HSR affordability in terms of expensiveness and economic equity. When we considered the differentiated tariff policy implemented in Europe and Japan, the affordability gap between China and the other countries is further enlarged. Moreover, inequitable distribution of HSR affordability between different income groups and social classes are found larger not only within China, but also higher when compared to the other sample countries.Finally, we conclude that China should implement differentiated HSR pricing system at a larger scale and greater extent based on the Ramsey pricing and Yield management principle to grasp the additional revenue from the high level income group/the developed region and alleviate the economic equity as well. Meanwhile, we also suggest the balance between HSR affordability for passengers themselves and the macro financial affordability for the country as a whole should also be considered in the future HSR pricing regime formulation.

Empowerment of Infrastructure Guarantee on Public Private Partnership (PPP) Projects in Indonesia: Implementation of the Balance Principle on the Effectiveness of the IIGF Guarantee Agreement

Infrastructure Guarantee is one of the government's much-needed support programs for PPP projects in Indonesia, with the goal of increasing creditworthiness, bankability, and investor trust. Until now, the usage of Infrastructure Guarantees has had its upsides as well as downsides, including complaints from private proponents about the lengthy evaluation process, payment of excessive fees, and the lack of scope of risk that the Indonesia Infrastructure Guarantee Fund Institute (IIGF) as guarantor can bear. In order to achieve an equal position between the Government Contracting Agency (GCA) and the Private Sector Entities (PSE) in the fulfilment of the PPP project in Indonesia, this study will examine the efficiency of the IIGF Guarantee Agreement using the principle of balance. The method of writing used in this paper is normative juridical method, which will be linked to the use of Guarantee Agreement in practice. The conclusion that can be drawn is that IIGF has provided a Guarantee Agreement in accordance with the balance principle, where the principle can also be seen in the risk allocation that has been agreed upon by the parties, apart from the arrangement of the Guarantee Agreement clauses. If an unbalanced position is later discovered, the parties can suggest action to restore balance so that the PPP project can be guaranteed until the concession time is completed.

FEATURES OF ETHNO-POLITICAL LEADERSHIP IN THE CONTEXT OF THE PARLIAMENTARY REPRESENTATION OF MINORITY ETHNIC GROUPS IN UKRAINE

Ethno-political leadership is an important indicator of the social and political representation of minority groups in a multicultural social environment. The most effective form of its implementation provides for the representation of the ethnic community at the level of the highest legislative body of the state. A number of countries in Central and Eastern Europe have developed their own models of such representation over the last past decades. They are implemented through guaranteed reservation of seats for representatives of ethnic communities, lower numerical thresholds for representation in parliament, inclusion of ethno-political leaders in the lists of national parties, single-member districts may provide sufficient minority representation as well. The relevance of the study of the ethno-political leadership in the context of parliamentary representation of ethnic minorities is objectively determined by the multi-ethnicity of Ukrainian society, declaration of Ukraine's integration into the EU structures and implementation of European democratic principles of governance.The subject of the research are public and political leaders, mostly heads of national-cultural societies, foundations, ethnopolitical parties. The author applies the method of electoral statistic analysis for parliamentary elections of 1990, 1994, 1998, 2002, 2006, 2007, 2012, 2014 and 2019. Synthetically generalized of minority representation in the Verkhovna Rada of Ukraine of all nine convocations. Emphasis is made on the political participation of representatives of the multi-ethnic regions in Ukraine (Crimea, Eastern Ukraine, Northern Azov, Southern Bessarabia, Bukovina, Transcarpathia).Adequate representationof people's deputies of Russian and Jewish ethnic origin has considered in the article. Among the ethnopolitical leaders of Jewish ethnicity, the figure of Kharkiv resident Olexander Feldman stands out, who since 2002 has invariably been a people's deputy of Ukraine. Vadim Rabinovych, the leader of the All-Ukrainian Jewish Congress is represented in parliament for only the last two terms. The most constant (since 1998 as a people's deputate) is the position of the Crimean Tatar leader, national democrat Mustafa Dzhemilev. A similar ideological orientation is taken by the head of the Mejlis of the Crimean Tatar people Refat Chubarov. The co-founder of the «Our Land» Party Anton Kisse is a stable ethno-political leader of the Bulgarians in Ukraine. The unbalanced position of the ethno-political leadership of the Romanian (Ivan Popescu) and the Hungarian (Ishtvan Haidosh, Vasyl Brenzovich) representatives is also has considered. It is indicated about the first steps at the parliamentary representation of the Azov Greeks in the person of Dmytro Lubinets.The author concludes about the low efficiency of parliamentary representation of ethnic minorities in Ukraine, which is caused by permanent changes in electoral legislation, negative electoral and engineering practice of gerrymandering and neglecting of European good practices of including minority ethnic groups in politics, which are defined in international documents.

Social Rights between Hard Law and Soft Law. A case study from European Union

After the Lisbon Summit of 2009, the whole matter of fundamental rights in the European Union has taken a new connotation. Local economic interests and social protests – in opposition to the “neoliberal agenda” of EU institutions – have played an important role in stopping the enforcement of the “Constitutional Treaty” and boosted an anti-Euro mobilization. In the meanwhile, the European bodies and transnational corporations have continued to settle a new and alternative basis for the integration. A radical shift can be observed, from the research of synthetic set of principles – as those established on the EU Charter of Fundamental Rights – to a deeply technical and detailed normative production. The regulation on safety and healthy workplaces is one of the best point of view to study this change. Far from calling into question the unbalanced positions between the parties in contemporary labour relationships, the European strategy for workers’ protection move through procedural issues and voluntary obedience to the soft law instruments. In the past, the legal doctrine described the creation of a multilevel architecture of institutions, sometimes implemented in a top-down approach. Along with this, recently, it was implemented the establishment of common organizational standards associated to a specific system of corporate governance to pursue a better integration between business and fundamental rights.
