Design and implementation of Train Running Gear Fault Simulation Tester based on DSP

This paper presented a train running gear fault simulation tester based on DSP and introduced its design principles and methods, described its hardware, software flow chart and the experimental results. This simulation tester was used a 16-channel digital to analog converter chip that made up the defects of common market function signal generator which was with less output channel and fixed mode. Each channel synchronous output was with the properties of real-time and scalability, the frequency and amplitude could be easily adjusted and so on.
