摘要
利用天棚控制原理和SIMPACK动力学软件建立了具有二系横向和垂向半主动悬挂车辆模型,分析在不同的半主动悬挂横向和垂向阻尼系数下,车体平稳性指标、构架加速度、轮对冲角和磨耗指数的变化情况,结果表明动力学性能之间存在多处相互矛盾的地方,在选择半主动悬挂横向和垂向阻尼系数时应合理安排,充分协调相互矛盾的动力学性能。
This paper established a lateral and vertical semi - active secondary suspension vehicle model by dynamics simulation software SIMPACK and sunshade control principle, then analyzed ride stability index, frame acceleration, attack angle of wheelset and wear index under the different lateral and vertical damping coefficient of semi - active suspension. The result shows that it exists contradictions between dynamics functions. While choosing the lateral and vertical damping coefficient of semi - active suspension, it should be arranged reasonably so as to moderate the conflicting dynamics functions well.
