地铁车辆悬挂参数优化与动力学性能评价方法

地铁车辆虽然分为A型和B型两大类,但各城市地铁车辆的技术与结构型式仍存在较大差异。目前对地铁车辆的动力学性能评价尚没有统一的方法,因此对各种形式的地铁车辆方案的对比也就没有一个统一的基础和前提。探讨利用线性化技术对地铁车辆悬挂参数进行快速优化的方法,并在大量干线机车车辆试验与仿真基础上,建议以一种线路不平顺条件作为这种方法的评价基础。此可用于不同方案地铁车辆的动力学评价。

Optimizing Method for Metro Vehicles Suspension Parameters and Performance Appraisement Method

In China there are only two types of metro vehicles, named type A and B, but vehicle structure and technology are very different from each other for different cities. At present there is no general method to estimate their performances on the same basis or presupposition, so it is hard to make contrast between different vehicle concepts. A linearization method is suggested for optimizing vehicle suspension parameters under the same track condition, which is obtained by huge of online testing and simulation for main line vehicles in this paper. Under this consideration performance appraisement and comparing for different types of metro vehicle becomes possible.
