| 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. |
