By using the theory of the finite element method, the wheel-rail high-frequency vibrations are studied. The finite element analysis of the wheelset structure is undertaken by use of the software ANSYS. The modal shapes and natural frequency of the wheelset are determined, and the dynamic response under random excitation are calculated. The response frequency spectrum of the wheelset can be obtained of different part.

铁路车辆在运行过程中,轮轨间的相互作用力是机车车辆产生高频振动的源动力。60年代英国科学家Wilson在他的一份报告中正式提出铁路高频振动的概念后,各国科学家开始了由轮轨作用力引起的轮轨高频振动的研究。1975年美国科学家Paul J. Remington [1] [2]提出了轮轨高频振动的基
