摘要
为掌握中低速磁浮列车通过小半径曲线时轨道梁应力分布情况和动力响应,该文以某中低速磁浮铁路试验线17m+28m+17m曲线轨道梁为例建立有限元模型,运用MIDAS/CIVIL进行了空间应力分析和动力响应分析,将静力分析的结果和时程分析的结果进行了比较。
In order to master the stress distribution and dynamic effects of track beams when medium-lows peed maglev trains are running on the small radius curve,taking a 17+28+17m curved track beam of a medium-low speed maglev trial line as an example,the finite element model is set up and the program MIDAS/CIVIL is used to analyze the space-stress and dynamic responses,and the comparison of results of static analysis and time history analysis is made.
