摘要

针对二系横向减振器和抗蛇行减振器在进行单独控制时出现的效果单一问题，提出了一种新型半主动协调控制方法，可协调直线和曲线线路条件下的车辆综合动力学性能。首先，建立了300公里级高速动车组的动力学模型，其中二系横向和抗蛇行减振器均进行了参数化处理；构建了横向和抗蛇行减振器的半主动控制模型，并模拟了动车组通过曲线轨道时的真实工况。经过仿真对比，发现单独对横向减振器施加半主动控制时，虽然能有效提高平稳性能，但会使安全性能恶化；而单独对抗蛇行减振器进行控制时，虽然使曲线通过性能提高，但会降低横向平稳性。有鉴于此，提出了一种针对横向减振器和抗蛇行减振器的新型半主动协调控制策略。经过仿真分析，发现该新型协调控制策略可有效解决上述问题，保证列车在曲线通过时，在确保安全性能的同时具有良好的平稳性能。

Abstract：

A new semi-active combination control is proposed in this paper, and the problems from semi-active lateral damper (SLD) control and semi-active yaw damper (SYD) control can also be solved. Firstly, a 300 km/h Electric Multiple Units (EMUs) dynamic model is built, and parameterized SLD and SYD models are achieved. Secondary, the semi-active control strategies are realized in SLD and SYD model, and some curve-passing conditions of EMUs are simulated. After comparing the two control results, SLD control can improve lateral ride index of vehicle but the safety index, and SYD control can improve safety index but the lateral ride index. Finally, a new SLD-SYD combination control strategy is proposed and applied in EMUs model. The simulation results show that the new control strategy can solve the problems above, and improve safety index and lateral ride index at the same times.

Key words： Electric Multiple Units semi-active control lateral damper yaw damper
