铰接式高速列车运行平稳性优化研究

Optimization Research on Running Stability of Articulated High Speed Trains

以高速列车为研究对象 ,采用面向对象的建模技术 ,建立了三车铰接垂向及横向非线性动力学模型 ,进行了时域和频域仿真计算。对铰接式高速列车的一系和二系悬挂参数对列车的垂向和横向运行平稳性的影响进行了研究。

With high speed trains as the research object and with application of the model establishment technology geared to the object, the vertical and crosswise non-linear dynamics models for the 3-car articulation are established, and the time domain and frequency domain simulation calculations are made. Research is made on the effect of the primary and secondary suspension parameters of the articulated high speed trains on the vertical and crosswise running stability of the trains.
