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
Effect of running wheel failure on stability and dynamic performance optimization of rubber-tired metro vehicle
摘要
Abstract
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.关键词
