Іntroduction of level crossing of new generation on the railways of Ukraine

An analytical review of the existing types of level crossing emphasizes the need of introduction of motors and reducers of a new type in it to minimize its size, reduce costs, improve the operation reliability of the crossing signal system, and thereby to improve the safety of railway transport in general. The control scheme of the railway level crossing remains the same, which facilitates the renovation stages and it does not require additional training of maintenance personnel. It is proposed to minimize the size and weight of the level crossing due to the introduction of DC motors with permanent magnets, which are cheaper and more reliable in operation against existing engines such as SL-571k and AIR 56V4B43. Also it is possible to reduce the weight of the level crossing due to the introduction of a planetary gear, which is more compact, it has reduced load on the shafts of the gear and the teeth of the wheels, increased gear ratio, reduced noise and longer life. The scientific basis of the introduction of direct current motors with permanent magnets and the planetary gear of the railway level crossing is given. A technique is developed to determine the primary parameters of the electric circuit for the chosen type motor, its working and mechanical characteristics. The mathematical model of the dc motor with permanent magnets has been improved due to the introduction of the methodology for definition the ratio of electric and magnetic constants according to the specified passport data, of the primary parameters and its working and mechanical characteristics, which was the scientific basis for the justification for diagnosing the engines of level crossing. It is allowed us to change the planned preventive maintenance technology on the maintenance according to the state of the objects: level crossing of railways of Ukraine and UIS countries in further.

Keeping the Power Flowing: A Commitment Throughout the HVdc and FACTS Life Cycles

An increasing number of high-voltage dc (HVdc) transmission links are being built around the world to efficiently and cost-effectively move large amounts of power from generation sites to distant centers of consumption. (Figure 1 shows a typical HVdc installation.) Similarly, flexible alternative current transmission systems (FACTSs) are increasingly being employed to boost power capacity and improve stability in existing grids the world over. These installations represent significant investments for owners, so it is essential that they are maintained in good condition with proper service strategies, onsite and remote maintenance, proper training of maintenance personnel, and, finally, after many years of successful operation, with upgrades to some parts of the installation.

A critical analysis of maintenance training regimes for an industrialised economy

As a management paradigm, it is accepted that maintenance management is less well developed than other management activities. One of the reasons for this underdevelopment can be traced to the way maintenance personnel are trained during their vocational, undergraduate and initial professional development phases. Historical records for all vocational training and all current undergraduate courses in Ireland that include a maintenance training element were reviewed. This course of research aims to discover the reasons why such training is poorly resourced, especially in an era where access to statistical modelling and predictive maintenance tools is commonplace. Ireland provides an interesting locus for the research as Ireland has a rich manufacturing topography. The research has shown that despite a well–funded third level and further education sector, Ireland still suffers from poor levels of maintenance personnel training. This research will be of interest to senior managers concerned with enterprise optimisation.

Prolegomena to the RAMI analysis of a conceptual LHCD system for DEMO

Future fusion reactors are asked to deliver large amount of energy in a continuative way to electrical power grids. In this frame it is very important to care the availability of the reactors since the preliminary phases of the design. Techniques to assure high levels of reliability must be extensively used and accurate programmes of maintenance must be studied, caring in the same time the training of maintenance personnel. Finally the layout of the reactor and of all its auxiliary systems must be carefully examined in order to assure an easy inspectability and a fast recovery of the power station after unavoidable failures. All the previously listed activities are summarized by the acronym RAMI (reliability, availability, maintainability and inspectability). The basics of the RAMI analysis for a conceptual LHCD system for DEMO are given in the paper.

Propellant Filling Equipment Simulation for Virtual Assembly

3D models of propellant filling equipment were constructed by using Autodesk Inventor, and assembly relation model was established by using connection graph method. Movement attribute was set and the models were romanced in Multigen Creator. A virtual scene of propellant filling equipment was set up, and assembly process demonstration and interactive operation simulation were achieved by using Vega Prime. Maintenance personnel training in the virtual assembly environment gets a good result.

Training of the maintenance personnel to prevent failures in aircraft systems

The aircraft maintenance process plays a vital role in aviation safety. The quality of the maintenance process and the qualifications of the aircraft maintenance personnel are important factors in the safety of aircraft. In this study the aircraft maintenance training model has been developed by especially taking in to account the EASA Part 66 regulations. The progression of the aircraft maintenance personnel training was investigated and suggestions to improve training process were given so as to prevent failures in aircraft systems.

An adaptive scheduling system with genetic algorithms for arranging employee training programs

An outstanding human resources system is one of the important competitive factors in modern enterprises. Employee training is a frequently used method for promoting the working capabilities for better human resources. Employee training programs cultivate personnel capabilities for enterprise operation. The training effect can be dramatically enhanced if curriculum is well designed and arranged. However, arranging curriculum is a difficult and lengthy task which enterprises traditionally devote a large amount of human and material resources to. We improved the process by proposing an optimal curriculum arrangement model in maintenance personnel training programs, and utilizing genetic algorithms as solution procedures. An adaptive computer aided training system for maintenance representative training was also developed to facilitate personnel training for machine tool industry.

The hygienic working practices of maintenance personnel and equipment hygiene in the Finnish food industry

The hygienic working practices of the maintenance personnel as well as the hygiene of the equipment in the food industry were investigated with questionnaires and microbial surveys. The protective clothing, washing of hands and tools as well as avoiding foreign bodies left on the production lines should be targeted when the hygienic working practices are developed for maintenance personnel. Based on the questionnaire to food processors, packaging machines, conveyers, dispensers, slicing and cooling machines were considered the most problematic pieces of equipment hygienically mainly because of poor hygienic design. In order to improve food safety, both the training of maintenance personnel in food hygiene and equipment design should be more emphasised.

Operating and Maintenance Experiences with Automated People-Mover Microprocessor-Based Train Control

Operating and maintenance experiences with automated people-mover microprocessor-based train-control systems are discussed, using as examples those systems operating in airports in Atlanta, GA, Orlando, FL, and Gatwick, London, since 1980. Advantages of micro-processor control are shown, using the example of vehicle-door operation. Operating experiences are described, illustrating how human interaction with the people-mover system was used to enhance vehicle dynamics, improve stopping accuracy, and enhance voice and graphic-sign announcements. It is shown how experience gained on passenger information transfer led to a solution in the development of the Downtown Miami people-mover system, where a vast amount of messages was required. System diagnosis and maintenance was refined through field experience; maintenance-personnel training was improved; new test equipment was developed; and for the first time, the true power of the computer was realized.

Computer Assisted Instruction Effectiveness in Maintenance Troubleshooting Training

The training of maintenance personnel has become a critical issue in recent years due to the rapid technological advancements of the systems to be maintained. The electronic technician must be efficiently trained to effectively troubleshoot faulty equipment. Previous research had indicated that students were not using logical troubleshooting strategies. The current research examined the performance effects of supplementing current technician training with a strategic troubleshooting computer assisted instruction course designed to teach logical troubleshooting strategies. The experimental design included two control groups and the treatment condition. Conclusions are drawn regarding the applicability and effectiveness of the CAI to the current Basic Electricity and Electronics training under study.

The impact of microelectronics on the utilization and training of maintenance personnel.

Microelectronic functional equivalents were defined for two operational systems—a ship's inertial navigation system and a torpedo guidance system—and, by means of maintenance burden analyses, the maintenance personnel, training and organizational requirements of the microelectronic and existing configurations were compared. Microelectronics reduced the amount of maintenance required by the ship's inertial navigation system by 84 percent, and the amount required by the torpedo guidance system by 18 percent, under existing maintenance philosophies. Specific conclusions were provided with respect to the impact of microelectronics on maintenance personnel and training requirements, and on the organization of maintenance activities.
