摘  要:建立了载货汽车5自由度模型,采用模糊控制方法对车身前后悬架进行主动控制。仿真结果表明,与一般的控制座椅悬架的控制方式相比,对车身悬架运用主动控制,不仅衰减座椅加速度,同时衰减了车身加速度。考虑减振性能和生产成本,对前、后悬架单独运用主动控制进行分析,得出了最佳的控制方案。A 5-DOF truck dynamic model was built up,and the active control was used in the front and back suspension which was based on fuzzy control. The simulation result shows that compared with the usual method of control which controls the suspension of the seat,the method which controls the body's suspension can not only reduce the seat's vibration,but also reduce the body's vibration. Considering the effect of reducing vibration and production cost,the analysis on front and back suspension was carried out separately by using the active control,and the best control method was also obtained.
