| 摘 要： | 针对地铁弹条的实际工况，采用UG建模，利用ANSYS-10．0仿真手段，对实际工作载荷下弹条中的应力和应变情况进行了计算机模拟．模拟结果显示：在压紧位移值和扣压量分别一定的情况下，改变对应的扣压量和压紧位移等边界条件后获得了弹条内部模拟应力分布和模拟最大应力值，模拟显示最大应力位置出现在地铁弹条的跟端弯曲圆弧位置；在两个影响因素中，压紧位移对弹条中的应力分布和最大应力值的影响更为显著．

| Abstract: | This paper presents a simulation analysis of stress and strain of an underground rail elastic bar with the commercial finite-element simulator ANSYS-10. The results show that under constant compression displacement or the fixed-plug-in displacement, the stress distributions are examined by varying the boundary conditions of the corresponding fixed-plug-in displacement or the compression displacement. In addition, in both group of scenarios the maximum stress is at the end of the arc of the elastic bar and exceeds the strength limit of 60Si2Mn. While both the compression displacement and the fixed-plug-in displacement affect the stress distribution and the maximum stress, it appears that the effect of compression displacement is much more significant. |
