| Summary: | 碩士 === 國立中正大學 === 機械系 === 89 === When rail vehicle is running in long time, the frictional heating effect between wheel and rail will be more acute. But general contact theories don’t include the research of thermal effect. To know clearly the distribution and magnitude of the practical force between wheel and rail of moving wheelset, we must consider the element of thermal effect.
In this paper we discuss the influences of thermal effect in contact theory to build a nonlinear thermal contact theory, and compare it with general nonlinear contact theory and experimental value. Under different driving condition and designing parameter, we observe and discuss difference of dynamic response between nonlinear thermal contact theory and Kalker's linear theory in the dynamic model of rail vehicle's single wheelset.
