ABSTRACT

With the rapid development of rail transportation, and the extensive application of traction motor, its repair work has already received increasing attentions. To ensure the repairing quality, it must undertake performance experiments. The study and design of the traction motor performance test-bed are provided in this paper. It is a special device which is used to carry out performance experiments and serve the traction motor of trains in Chongqing light rail.
Based on the design gists, such as the test procedures for three-phrase induction motors (GB/T1032-2005) , Chongqing light rail’s actual situation and requests and other correlative standards, the structure design of platform, hardware design of co- mputer testing system and software exploitation of the traction motor performance test-bed are given in this paper. Firstly, the structure and operational principles of the traction motor are analyzed in detail, and then motor testing methods that are popular presently are compared. The method of the automatic testing system with sensor has been regarded as the one suitable for our test-bed and its testing principium and mat- hematical model have been provided. Then, starting in the general design model of measuring and controlling system, this paper has put forward the collectivity design of the computer measuring system of the test-bed and done something to strengthen the anti-jamming ability of the system. This paper has used Visual Basic 6.0, Object Oriented program language, to exploit the software and realized the communication between host computer and sensors through MSComm control with automatically sampling, measuring and processing data. The software combines the Visual Basic 6.0 and Microsoft office products to design, preview and print the experimentation reports and realize the storage of real-time and historical data.
The traction motor performance test-bed studied and designed in this paper has satisfied the function requests, achieved anticipative effect and solved the actual problems during the building of Chongqing light rail. It also gives references to the design of such kind of device.
