摘要

以半体悬式和弹性架悬式200 km/h 高速动力车为研究对象，分别建立了动力学分析模型，进行2 种方案的动力学性能对比。结果表明二者均能满足运行速度200 km/h 的运行要求，且对动力车曲线通过性能影响不大。但采用半体悬式方案时，动力车非线性临界速度高于采用弹性架悬式方案，其垂向平稳性指标比弹性架悬略差，直线运行平稳性能则优于弹性架悬方案。

Abstract

Dynamic models of 200 km/h high-speed power cars with semi-body and flexible suspensions were established respectively, the dynamic performance of which was compared and analyzed. It was showed that both of the suspension mode satisfied the speed requirement of 200 km/h and affected car’s curve passing performance little, and the high-speed power car with semi-body suspension had higher nonlinear critical speed and better straight riding quality but worse vertical riding comfort.
