走行轮失效对胶轮地铁车辆稳定性影响及动力学性能优化OA
Effect of running wheel failure on stability and dynamic performance optimization of rubber-tired metro vehicle
针对胶轮地铁车辆在运行过程中存在走行轮胎漏气、径向力过大所导致的爆胎等问题,建立了胶轮地铁车辆动力学模型,开展了走行轮失效工况下车辆的动力学性能分析.利用Sobol法,对影响胶轮地铁车辆运行稳定性的主因子进行了敏感性分析.围绕胶轮地铁车辆走行轮爆胎的问题,基于非支配排序遗传算法(NSGA-Ⅱ),对影响胶轮地铁车辆动力学性能较大的悬挂参数进行优化研究.研究结果表明:在走行轮失效工况下,胶轮地铁车辆的运行稳定性和曲线通过性仍能得到满足;通过参数协调匹配优化,减小了胶轮地铁车辆的走行轮径向力,改善了胶轮地铁车辆的动力性能.
To solve the problem of tire blowouts caused by tire leakage and excessive radial force during the operation of rubber-tired metro vehicle,the dynamic model of rubber-tired metro vehicle was established,and the dynamic performance analysis of vehicles under the condition of running wheel failure was carried out.By Sobol method,the sensitivity analysis was conducted on the main factors affecting the operational stability of rubber-tired metro vehicle.Based on the non dominated sorting genetic algorithm(NSGA-Ⅱ),the optimization study was conducted on the suspension parameters which have significant impact on the dynamic performance of rubber-tired metro vehicle.The results show that under the condition of running wheel failure,the operational stability and curve possibility of rubber-tired metro vehicle can still be met.By coordinating and optimizing parameters,the radial force on the running wheel of rubber-tired metro vehicle can be reduced,and the power performance of the rubber-tired metro vehicle is improved.
