Numerical simulation of temperature and stress fields for brake disc and coupling used on high-speed locomotive of 200 km/h

According to heat transfer principle,this article establishes thermal transmission mathematical model for brake disc on high-speed locomotive.With ANSYS finite element program,it simulates the value of temperature and stress fields for brake disc and coupling on the locomotive of 200 km/h.At the same time this article proves the high accuracy of numerical simulation by test results from bench test of 1∶1.It also probes into the general rules of instant temperature and stress fields for brake disc and coupling according to the simulation results.
