用拉普拉斯变换方法研究轮轨滑动引起的温升

Temperature Rise Due to Slip between Wheel and Rail

用拉普拉斯变换方法研究了由于轮轨之间的滑动所造成的温升。假设轮轨接触的压力为赫兹椭圆分布，且热源为瞬时静态热源。

The temperature rise due to slip between wheel and rail is obtained by Laplacetransform method. It is assumed that the pressure distribution at the wheel-rail contact isHertzian elliptical and that the fast moving heat source can be approximated to an instanta-neous static source.
