抬轮器对工程车过道岔动力学性能的影响

Influence of Wheel Lifter on Dynamic Performance of Engineering Vehicle Passing Through Turnout

基于多体动力学软件建立工程车、轮轴故障工程车、抬轮器、9号右开道岔模型,分析轮轴故障工程车一位轮对轮轴故障时,安装抬轮器后侧向过道岔的行车安全性。仿真结果表明,轮轴故障工程车安装抬轮器后能够以限速30 km/h侧向安全通过9号道岔;一位轮对在添加抬轮器后,轮轴故障工程车过道岔的速度对车辆的动力学性能影响较明显;一位轮对在被抬高5、10、40、80、120 mm以30 km/h侧向过道岔时,较低的抬轮高度一定程度上对车辆动力学性能有益。

Based on the multi-body dynamics software,the models of engineering vehicle,axle failure engineering vehicle,wheel lifter and No.9 right turnout were established,and the driving safety of one position wheelset of axle failure engineering vehicle with wheel lifter was analyzed.The simulation results show that:after installing the wheel lifter,the axle fault engineering vehicle can safely pass through No.9 turnout at the speed limit of 30 km/h;after adding the wheel lifter,the speed of the axle fault engineering vehicle passing through the turnout has a significant impact on the dynamic performance of the vehicle;when the axle fault engineering vehicle is lifted 5,10,40,80,120 mm to 30 km/h,the lower wheel lifting height has a certain impact on the dynamic performance of the vehicle dynamics performance is beneficial.
