摘　　要：视扣件为纵、横方向无长度无质量的弹簧单元，建立起了轨道结构动力响应的有限元计算模型．分析了轨道结构纵、横方向在５００Ｈｚ频率范围内的位移响应．通过计算，表明轨道动力分析的有限元法是分析轨道结构动力特性的有效方法．Taking the fastener as a spring element without the length and mass in the lon-gitudinal and traverse directions,the mechanical model with finite elements for railway track vibrations is set up.The displacement response of railway track in longitudinal and transver-sal directions within the range of 500 Hz is analysed then. It follows from the calculation that the method presented provides a move effective approach to the analysis of railway track vi-brations.
