摘　　要：利用有限元方法对时速250km/h高速火车新型空心车轴重要参数进行了分析,确定了轮轴压装过盈量,以及内孔径取值最佳范围,通过模态分析得出轮对自振频率。说明其具有足够的强度和刚度,可以满足高速运行的要求。In this paper, by using finite element method , important parameters of newtype hollow axle used on high speed train with max speed 250 km/h is analyzed, optimal magnitude of interference on pressure mounting of wheelset and proper aperture size of alxe is determimed. Natural frequency of vibration of wheelset is obtained by module analysis. It is shown that the hollow axle is provided with sufficient strength and stiffness ,which meets requirement of high speed running.
