| Abstract: | 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. |
