摘要
为更有效地提高悬架平顺性,试验车辆采用了二级可调阻尼减振器,在Matlab/Simulink软件中建立与其对应的汽车半车仿真模型;以车身加速度为评价指标,通过仿真和试验结果比较,验证建模的正确性。然后,运用遗传算法设置合适的控制参数,优化建模;车身加速度优化前后的性能对比结果表明,遗传算法能够有效地提高车辆平顺性,为后续控制系统的研发奠定了一定的基础。
In order to improve the suspension ride performance ,2 level-adjustable dampers were adopted on test vehicle, and 1/2 vehicle simulation model was built in Matlab/Simulink. Based on evaluation target on acceleration of body ,validated the model＇ s correctness by comparison between simulation and tost results. By applied of Genetic Algorithm （GA） and optimized the control parameters,made the simulation model optimization ; and GA was proved its advantage on enhance vehicle ride performance by comparison the body acceleration before optimization and after, and established the foundation on development of control system in future.
