| 摘 要： | 针对空气主动悬架在高频段的振动问题,设计一动力吸振器,建立带动力吸振器的空气主动悬架的1/4车辆动力学模型,结合最优控制相关理论,对带动力吸振器的空气主动悬架控制器进行设计。运用Matlab编程功能对动力吸振器参数进行优化并得到了最优参数。应用Matlab/Simulink软件对带动力吸振器的空气主动悬架的动力学模型进行频域和时域的仿真研究,并与不带动力吸振器的主被动空气悬架进行对比分析。结果表明带有动力吸振器的空气主动悬架在高频段的减振性能明显优于被动空气悬架和常规空气主动悬架。

| Abstract: | Dynamic vibration absorber is designed to solve the problem of vehicle vibration during high frequence stage,and then a quarter of vehicle dynamic model is established based on the pneumatic active suspension with dynamic vibration absorber.Combining with the optimal control theories,a controller for the pneumatic active suspension with dynamic vibration absorber is designed.Meanwhile the parameters of dynamic vibration absorber is optimized and the optimal value is acquired by applying programming of the Matlab.Afterwards simulation study is carried out for dynamics models of the suspension with dynamic vibration absorber in frequency domain and time domain and compared with that without dynamic bibration absorber by Matlab/Simulink,which results show that the vibration control performance of the pneumatic active suspension with dynamic vibration absorber during high frequency stage is more superior to passive pneumatic suspension and normal pneumatic active suspension. |
