摘要
针对磁悬浮列车转向架进行有限元分析时悬浮面的边界条件设置为全约束,但表现出的工况与实际工况不符的问题,提出一种以弹性支撑为边界约束条件,以列车轻量化为目标的设计分析方法。通过SolidWorks软件进行了新型高温超导磁悬浮转向架模型的设计,并根据磁悬浮列车不同的运行工况,分析了转向架整体强度以及杜瓦横梁与磁轨之间的最小间距。结果表明,此转向架满足设计要求,为后续优化计算提供了分析依据。
Aiming at inconsistent problem with the actual working condition when the boundary condition of the suspended surface was set to the whole constraint in the finite element analysis of the maglev train bogie, a new method with the boundary constraint of elastic support and on the purpose of lightweight train was brought out. A new magnetic levitation bogie of high temperature superconducting was designed by SolidWorks software, and according to the different operating conditions of the maglev train, the overall strength of the bogie and the minimum spacing between the Dewar beam and the track were analyzed. The results showed that the bogie met the design requirements and provided the basis for the subsequent optimization calculation.
