摘　　要：制动性能作为评价车辆减速器的重要指标,通常需在驼峰编组站通过实际测量的雷达测速曲线获得。为进一步优化减速器制动性能的获取方式,提出采用虚拟样机仿真的方法对车辆减速器建模并进行动力学分析。首先,基于车辆减速器的工作原理,结合车辆减速器的结构参数和运行状态,构建“车辆-钢轨-减速器”的刚柔耦合动力学模型;其次,以21 t轴重、走行速度5 m/s(18 km/h)的车辆为例,利用仿真模型分析减速器的制动能力。结果表明:该模型的分析结果与减速器制动性能的理论值和实测结果相吻合,可为后续减速器的设计和改进提供参考。As the main performance index of evaluation of retarder,braking performance usually needs to be obtained through actual measurement of radar speed curves at hump marshalling stations.In order to further optimize the acquisition of braking performance of the car retarder,the virtual prototype simulation method is used to model the car retarder and carry out dynamic analysis.Firstly,based on the working principle of car retarder,combined with the structural parameters and operation state of car retarder,the rigid-flexible coupling dynamic model of“vehicle-rail-car retarder”is constructed.Then,taking the vehicle with 21 t axle load and running speed of 5m/s(18 km/h)as an example,the braking capability of the car retarder is analyzed by simulation model.The results show that the analysis results of the model are in agreement with the theoretical value of the braking performance of the car retarder and the actual test results,which can provide reference for the subsequent design and improvement of the car retarder.
