APPLICATION OF TEST METHODS USING VIRTUAL TESTRIG TO VERIFY PERFORMANCE OF VIRTUAL RAIL WAY VEHICLE MODEL

초록

Competition with other communication like ground and air transport systems as well as other rail company forced to rail engineers use virtual engineering techniques. Virtual engineering techniques are based on progressive computer software development. But they don’t have any verification method of virtual model. On the other hand physical prototypes are proven by simple test like wedge test and X-factor test. In this paper we suggest the application of test methods using virtual test-rig to verify performance of virtual railway vehicle model. Before using the virtual model to analysis railway vehicle dynamic performance, rail engineers should verify their virtual model. That is very important thing to guarantee reliability of virtual model, to shorten development time and cost.
