摘要

摘要: 建立了一种新型动力总成磁流变悬置的动力学模型，并对其进行动态特性试验。通过数值拟合方法对试验数据进行拟合，得到了电流与可控阻尼力的关系式，为磁流变悬置的控制应用提供了理论模型。考虑车辆悬架系统的等效刚度和阻尼，建立了磁流变半主动悬置系统模型。设计了磁流变半主动悬置Fuzzy-PID切换控制系统，对不同工况下磁流变半主动悬置系统的隔振特性进行了仿真研究，结果表明应用Fuzzy-PID切换控制的磁流变半主动悬置系统具有良好的隔振效果。

Abstract: The dynamic model of a new type of powertrain magnetorheological (MR) suspension system was built and experiments on its dynamic characteristics were carried out. The numerical fitting method that establishes the relationship between the current and the controllable damping force is applied as a theoretical model to control the MR suspension system. With the equivalent stiffness and equivalent damping of the powertrain MR suspension system considered, the model of MR semi-active suspension system was constructed. The fuzzy-PID switching control strategy was designed for the MR semi-active suspension system. Then its vibration isolation performance was simulated under different working conditions. The simulation results show that the MR semi-active suspension system has good effects on vibration isolation with the use of the fuzzy-PID switching control strategy.
