摘  要:
基于可调阻尼减振器的试验结果,拟合了可调阻尼减振器阻尼系数与步进电动机转角之间的非线性关系,建立了阻尼非线性半主动悬架数学模型,设计了模糊动态最优控制策略,研制了阻尼非线性半主动悬架系统控制器,在仿真的基础上,进行了实车道路试验。结果表明,阻尼非线性半主动悬架模型更接近实际模型,有效改善了车辆的乘坐舒适性、行驶安全性,协调了整车综合性能。

摘  要:
Based on the test results of tunable damper,the nonlinear relation was fitted between the damping and the angle of the stepping motor.The mathematical model of semi-active suspension with nonlinear damping was built and fuzzy dynamic optimal control strategy was designed.The controller of semi-active suspension with nonlinear damping was developed.On the basis of the simulation,the actual road test has been done.The results showed that the model of semi-active suspension with nonlinear damping was closer to the actual model,the comfort and the security were effectively improved and vehicle performance was coordinated.
