摘要
为了在改善车辆平顺性的同时获得较好的馈能效果,基于液-电馈能式油气悬架系统中液压马达排量对车身垂向加速度和馈能功率的影响,提出一种改进型天棚阻尼半主动控制算法。在馈能式油气悬架的1/4车辆模型中,以随机路面为激励信号,对被动控制、传统天棚阻尼半主动控制和改进型天棚阻尼半主动控制三种控制方算法的进行了仿真对比。结果表明:与另外两种控制算法相比,改进型天棚阻尼半主动控制算法有效地兼顾了车辆的平顺性的和悬架的馈能功率。
To balance the vehicle ride comfort and vertical vibration energy regeneration,a modified skyhook damping control algorithm was proposed. It was used in a hydraulic-electrical energy regenerative semi-active hydropneumatic suspension system, based on the effects of the hydraulic motor displacement on the car-body vertical acceleration and electrical power recovered. By simulations on a quarter car model,the results of the passive control,traditional sky-hook damping semi-active control and modified sky-hook damping semi-active control were compared. The results show that the modified skyhook damping semi-active control algorithm can effectively improve the vehicle ride comfort with relatively good energy regeneration.
