Research on the Integrated Design Method of the Compliant Mechanism with Electromagnetic Actuators

An integrated design method of the compliant linear positioning device (CLPD) was researched, which was composed of a compliant guide mechanism and two electromagnetic actuators.

Advanced Integrated Design Method for Fatigue Assessment of Large Elastic Ship Structures

This paper is focused on an advanced method for ship structures fatigue assessment. The ships classification societies standard rules for fatigue analysis are based on simplified procedures, with wave induced loads obtained by linear oscillation analysis (low frequency, around 0.1 Hz), or equivalent statistical wave loads. In the case of large elastic ship structures, with hull length over 150 m, the global wave induced vibration response (high frequency, around 1 Hz) becomes significant. The developed integrated method for large ships fatigue assessment includes three interlinked analyses, as follows: the hot-spot stresses evaluation by 3D finite element models, wave induced loads by short term linear and non-linear hydroelastic dynamic analysis, ship service life and fatigue assessment by damage cumulative ratio method. As testing ship, it is considered a double hull LPG Liquefied Petroleum Gas carrier, with total length 239 m, for a set of structural details with stress hot-spots. Based on the non-linear hydroelastic wave loads, the integrated method of fatigue assessment becomes more accurate, predicting for the amidships structure 14 years of ship service life, instead of over 20 years according to the rules standard approach, so that the confidence on ship structure fatigue evaluation can be increased in the design process.

An integrated method for flexible platform modular architecture design

Product platform modular architecture identification is the most critical process to support the incremental design of derivative instances. In order to solve the inflexibility in a single modular or scalable platform of complex mechatronics products, an integrated product modularisation scheme based on flow analysis, design structure matrix (DSM) and fuzzy clustering is proposed to compose a flexible platform. The definition of flexible platform is explained and internal mappings among functions, components and modules are set up. DSM for a kernel product is constructed by the flow analysis between the leaf components in design bill of material. An improved scaling by minimising a convex function algorithm is developed to transform the DSM to vectors in two-dimensional spaces, and the vectors are clustered using the traditional fuzzy c-means algorithm. Cluster centre components are selected to identify modular types with respective functional features. Thus, the internal relationships between components can be modelled with flow analysis-based DSM in a clear format, and the proposed DSM transformation and clustering algorithm identify the modular architecture for a flexible platform in a lower computational complexity. A numerical example and computational comparisons are also given to illustrate the proposed concept and the effectiveness and efficiency of the proposed approach.

A Design Method for Thin Film Patterning Process via Lift-Off Technique

Thin film patterning by a lift-off method is effective from the viewpoint of cost performance and environmental issues. As a solution to the problems of conventional lift-off methods, the inversely-tapered resist profile with interstice was proposed and its fundamental feasibility was experimenatally proved. The resist profile still needed to be designed properly to solve the problems completely, and therefore a design method was also suggested. The method presupposes that conditions of deposition process have been already determined. However, actually, the conditions relate closely to the design of resist profile and wrong conditions may result in undesirable or infeasible design result. This paper proposes an integrated design method of the thin film patterning process considering design of both resist profile and deposition conditions.

Toward a qualified process for coastal models: Integrated Development of Applied Systems for Coastal Management (IDeASyCoM)

This paper describes a generalisation of the integrated design method for environmental modelling. The wide range of processes determining coastal morphodynamics and their temporal and spatial variability give rise to a large number of possible scenarios that can be addressed using modern sediment-transport models. The exhaustive assessment of detailed model functionalities is time and resource consuming because of a priori decision making. Methods to prioritise the functionalities to be addressed are necessary. The Integrated Development of Applied Systems for Coastal Management (IDeASyCoM®) based on a decision-support system has proven to be efficient for identifying coastal managers' needs and defining priorities as well as for handling and capitalising on existing knowledge.

Integral Design and Analysis of Passive Magnetic Bearing and Active Radial Magnetic Bearing for Agile Satellite Application

In this paper, the design and development of a magnetic bearing system which consists of passive magnetic axial/tilting bearing and active two-axial radial magnetic bearing (RMB) used in magnetically suspended wheel (MSW) or magnetically suspended control moment gyroscope (MSCMG) for agile satellite application is presented. The passive axial/tilting magnetic bearing supplies an axial position stiffness to stabilize the rotor in the axial direction and a tilting stiffness to restrain the rotor when subjected to gyroscopic torque. The active two-axis radial magnetic bearing with bias permanent magnet stabilizes the rotor on the axes perpendicular to the rotation axis. Considering the complex distribution of flux density the system performance cannot be accurately analyzed by the conventional magnetic circuit method because of the high coupling between force and moment produced by the axial magnetic axial/tilting bearing and RMB. To analyze the coupling problem of the force, moment, position stiffness, and tilting stiffness between the passive magnetic axial/tilting bearing and RMB, an integral design and analysis method based on three-dimensional finite-element method is presented. An example is given and analysis results prove that the high coupling occurs on the radial direction and the light occurs on the axial and tilting directions orthogonal to the spin axis. Then the linearized model is given in this paper.
