The conception of the experimental rail vehicle

摘要

Purpose: The article deals with the advance configuration and the installation of vehicle components to the experimental rail vehicle powered by the traction battery. Particularly the paper focus on the research problems of the construction of the experimental rail vehicle (bogie), the structure of electrical equipment of experimental rail vehicle (traction drive, control system, power supply system and the research problems of the influence between the different systems placed on the experimental rail vehicle are mentioned as well.Design/methodology/approach: The design of the experimental rail vehicle which has a foursome mechanically independent drives and each drive has own DSP controller, is specific. The mentioned configuration ensures the coordination of the traction forces between traction drives, which create one bogie with independently rotating wheels, provides the necessary energy flows. For the reason of the effects of the control to running characteristics the experimental rail vehicle has a lot of sensors and the other measuring devices.Findings: The problems of EMC - influence elimination of traction drive with PMSMs, control and measurement are solved. The sophisticated structure of the conception of the vehicle, which is expected to minimization of influence to the sensitive precision measuring equipment from, was designed during the development of the experimental rail vehicle (the minimization was achieved by LCD and LC filter modules).Research limitations/implications: The vehicle with four PMSMs form the whole traction vehicle drive with the total nominal power of 5 kW because of the budget is limited.Originality/value: The special conception of rail vehicle, which is mechanically designed by Rolling Stock Research Institute, is constructed at the JPTF for the purposes of experimental research on vehicles with independently rotating wheels.
