| 摘 要： | 电动助力转向系统（EPS）与汽车性能的协调是其装车时考虑的首要因素之一。应用多体动力学软件ADAMS建立电动助力转向及汽车动力学模型,提出兼顾转向轻便性和汽车侧向行驶稳定性的目标函数。基于粒子群优化算法（PSO）对EPS系统参数进行优化,得到最优解。最后,进行仿真分析和实车试验。结果表明,EPS参数全局优化后,转向盘操纵力矩峰值降低32.2%,侧向加速度峰值降低29.1%,最大超调量降低41.5%,汽车转向轻便性和侧向行驶稳定性均得到明显改善。

| Abstract: | The coordination between electric power steering(EPS) system and vehicle is one of the key factors when loading tests.The simulative model of EPS and vehicle was established by multi-body dynamics software ADAMS.The objective function considering steering portability and lateral stability of vehicle was proposed.The key parameters of EPS system were optimized based on particle swarm optimization(PSO),and optimum solutions were obtained.Simulation analysis and real vehicle tests were made.The results show th... |
