摘要: 在建立履带式车辆悬挂系统两自由度运动微分方程的基础上,采用LQR控制算法仿真分析了某型履带车辆悬挂系统在实测六条不同路面激励输入下,全闭环反馈对整车振动的控制效果;结合Hrovat限界最优半主动控制算法和车辆悬挂系统振动的半主动控制策略,仿真分析了磁流变阻尼器对整车振动的控制效果,并与LQR控制结果作了比较;通过对比半主动控制力跟踪主动控制力的情况,分析了磁流变半主动控制能够很好地逼近主动控制的原因;得出了采用磁流变阻尼器实现履带车辆悬挂系统半主动振动控制的技术途径是可行的结论。

Abstract: A simulation analysis of the semi-active control of tracked vehicle suspension system was giv?en using magnetorheological fluid dampers. After formulating the equations of motion for suspension system considering two degrees of freedom, the control effectiveness of full state feedback controf' of LQR was calculated with the input of six measured road surface excitations. Simulation of semi-active control utilizing magnetorheological fluid damper with limited optimal Hrovat control algorithm and the semi-active control strategies proposed was carried out, and the results of the two control methods were compared. T. he effectiveness of semi-active control force tracking active control force was conducted and the analysis of active force was given, showing why semi-active control can replace active control. Simulation results show that magnetorheological fluid damper in the semi-active vibration control of suspension system of tracked vehicle is feasible.
