摘要
为了改善列车高速运行时的乘坐舒适性,采用车辆二自由度模型对开关型和连续型两种控制策略进行对比分析,根据传递特性分析结果提出了混合控制策略,同时研究了调整系数对混合控制策略的影响.为进一步验证控制策略的有效性,建立了UM与Simulink联合仿真整车模型,对二系横向减振器施加此控制策略,并进行了仿真分析.结果表明:在调整系数选取适当的情况下,该控制策略可同时兼顾开关型和连续型两种控制策略的优点,降低了车体横向加速度,改善了列车的横向平稳性.
In order to improve the ride comfort of trains at high speed,the semi-active h ybrid control of a train suspension was studied.A two-degree-of-freedom vehicle model was established to analyze and compare the on-off control strategy and continuous control strategy.Based on the analyses of transmission characteristics,a hybrid control strategy was proposed,and the influence of adjustment coefficient on the hybrid control strategy was studied.In order to verify the effectiveness of the control strategy,a full-vehicle model was established based on UM and Simulink.The control strategy was applied to the secondary lateral shock absorber,and the simulation analysis was carried out.The results showed that the hybrid control strategy can take into account the advantages of both on-off and continuous control strategies,the lateral acceleration of the car body is reduced and the lateral stability of the train is improved,when the adjustment coefficient is selected properly.
