高速磁浮线路道岔钢梁移位过程及其数值分析

Shift Process and Numerical Analysis of High Speed Maglev Switch Change

高速磁浮线路道岔主体结构为一连续箱形截面钢梁。采用端部刚接和铰接两种支座条件、梁单元和壳单元两种计算模型,从结构受力角度对道岔切换方案进行了数值计算,并对计算结果进行了比较分析。在进行计算时,如果不要求得到截面上的细部结果,可用梁模型进行计算;如果要得到截面上的细部结果,就必须采用壳模型进行计算,获取相应的数据。

The structure of high speed maglev switch is a continuous girder of box section.Adopting two kinds of support conditions,namely the fixed bearing support and joint,and two kinds of models,the beam model and shell model,this paper makes a numerically calculation of the structure force of different shift processes and compares the calculation results.This research will provide detail reference data for switch design.
