摘要
建立了整车悬架系统的三维模型,根据试验数据得出了前后悬架弹簧的非线性特性曲线。前后悬架减振器均采用磁流变减振器,采用Bouc-Wen参数化模型为其阻尼力模型。采用模糊控制算法为整车半主动控制算法,采用ADAMS和Matlab联合对整车平顺性进行仿真。结果表明,采用模糊控制算法控制磁流变非线性悬架可提高整车的平顺性。
The three-dimensional model of the complete vehicle suspension system is built,the nonlinear characteristic curves of the springs in the front and rear suspension are acquired according to the experiment data.The magneticcurrent ahernation absorbers,are adopted for the front and rear suspension absorbers.and adopt Bouc-Wen parameter model as damping force model.We adopt fuzzy control algorithm as semi-active control algorithm of complete vehicle,and adopt ADAMS and Matlab to simulate ride performance of complete vehicle.The results show that magnetic-current alternation nonlinear suspension controlled by fuzzy control algorithm can improve ride performance of complete vehicle.
