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.建立300 km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.%A new semi-active combination control technique was proposed to coordinate the semi-active lateral damper (SLD) control and semi-active yaw damper (SYD) control.The dynamic model of a 300 km electric multiple units (EMUs) was built,including the parameterized models of SLD and SYD.At first,the semi-active control strategy was realized by using individually the model of SLD or SYD,and some curve-passing conditions of EMUs were simulated.Comparing the results of the two types of controls,it is found that the SLD control can improve the lateral ride index of vehicle but may worsen the safety index,and the SYD control can improve the safety index but may worsen the lateral ride index.Finally,a new SLD-SYD combination control strategy was proposed and applied in the EMUs model.The simulation results show that the new control strategy can improve the safety index and lateral ride index at the same time.
