摘要


用联合仿真方法分析了基于磁流变(Magnetorheological, MR)阻尼器的两种半主动控制策略对8车编组高速动车组动力学性能的影响。建立了考虑非线性悬挂系统和MR阻尼器的8车编组高速动车组模型,并利用试验数据进行了验证。在进行MR阻尼器性能试验的基础上,利用多项式模型进行曲线拟合,得到了MR阻尼器的9阶多项式模型。通过ADAMS和Matlab联合仿真的方法,设计了开关控制器和改进型开关控制器,对基于MR阻尼器的高速动车组二系悬挂系统横向半主动减振器进行仿真分析。仿真结果表明:对比被动控制,开关控制和改进型开关控制作用下的车体横向加速度均方根值最大分别降低14.85%和22.58%,车辆横向运行平稳性指标最大分别降低4.23%和7.95%。由此可见,改进型开关控制的减振效果更佳。

Abstract

The effects of two kinds of semi-active control with Magnetorheological (MR) dampers on dynamic performance of 8-car high-speed Electric Multiple Units (EMU) were analyzed by co-simulation method. High-speed EMU model which includes nonlinear suspension system and MR damper was built, and verified with experimentation results. Based on performance experiment of MR damper, 9-order Polynomial model of MR damper was obtained by using polynomial model for curve fitting. Through co-simulation using ADMAS and Matlab, on-off controller and improved on-off controller were designed respectively, and the lateral semi-active damper of second suspension system was analyzed for high-speed EMU with MR damper. The simulation results show that the root mean square value of lateral acceleration of vehicle decrease 14.85% and 22.58% respectively, the index of lateral running stability of vehicle decrease 4.23% and 7.95% respectively under on-off control and improved on-off control compared to passive control. Therefore, the improved on-off controller has a better effect on vibration reduction.
