磁浮列车在坡道段运行时动态特性分析

Dynamic Analysis of Maglev Train Running on the Ramp

磁浮列车系统以转向架作为单元,对每个转向架的控制又是独立的,而在对转向架的四点悬浮控制中,左右模块是对称的,因而可以用一个模块的两点悬浮模型来代替整车进行悬浮控制分析。结合八达岭旅游示范线的CMS-3型磁浮列车及其中试试验线,建立了磁浮列车两点悬浮模型,并对磁浮列车在坡道段运行时的动态特性进行仿真,同时比较了两种不同的悬浮控制方案的控制特点。仿真结果表明,相比于单点悬浮模型,所建立的两点悬浮模型与实际磁浮列车在坡道段运行的动态特征相吻合;采用相对速度的控制方案更有利于实现稳定,降低外部扰动的影响。

Bogy is the basic unit of the maglev system,which is controlled independently.In the four point control of bogies,the controllers of the left side are symmetric with that of the right side,so the two-point levitated model can be used to analysis the character of magnetically levitated control instead of the whole train.By using the CMS-3 Maglev Train and the experimental rail track developed for Badaling travel line,two-point levitation model is built,the dynamic character moving on the ramp is simulated,an...
