钢轨接头强度的有限元分析

Finite Element Analysis of Strength of Rail Joints

提出钢轨接头强度计算的有限元方法.该方法采用的计算模型将钢轨接头看作半无限长连续弹性点支承梁用弹性铰连接的结构.给出了钢轨接头强度计算的方法和算例.此外,根据算例还给出了柔度系数及轨道参数对钢轨接头强度的影响.

A finite element method to calculate the strength of rail joints of railway track is presented.The adopted model is a structure in which the rail joint is considered to be two semiinfinite long beams,on discrete elastic supports,joined with an elastic hinge.The illustrative examples for calculation are given.In addition,the influence of flexibility coefficient and rail track parameters on the strength of rail joint is presented. 
