摘　　要：跨座式单轨车辆采用胶轮走行,弓网接触状态不易控制,受电弓受流滑块磨耗严重。为降低受流滑块磨耗,文章在建立“车-弓-网”系统动力学仿真分析模型的基础上,利用灵敏度分析方法针对相关车辆动力学参数对弓网耦合作用力的影响程度进行分析;将弓网接触力均值作为优化目标,采用非支配排序遗传算法(NSGA-II)优化车辆动力学参数。研究表明,走行轮胎、导向轮胎的刚度对弓网接触质量影响较大,参数优化后各车速下弓网接触力标准差均有一定程度下降,通过优化轮胎径向刚度参数可以改善跨座式单轨车辆受电弓滑块的磨耗问题。Because straddle monorail vehicles run on rubber wheels, the contact status between the pantograph and the catenary is hard to control, and the abrasion on the current-receiving sliding block on the pantograph is serious. In order to reduce the abrasion on the sliding block, a sensitivity analysis method was used in this paper to analyze the influence degree of vehicle dynamics parameters on the coupling force of pantograph and catenary based on the dynamic simulation analysis model of "vehicle-pantograph-catenary" system.The average value of the pantograph-catenary contact force was considered as the optimization objective, and dynamics parameters of the vehicle were optimized by non-dominated sorting genetic algorithm(NSGA-II). The results show that the rigidness of the running tires and the guide tires has a great influence on the pantograph-catenary contact quality, and the standard deviation of the contact force decreases to a certain degree at different speed after parameter optimization. The abrasion problem of pantograph sliding block of straddle monorail vehicle can be improved by optimizing the radial rigidness of tires.
