中文摘要：
针对被动悬架系统侧倾稳定性较差的问题,提出采用磁流变半主动悬架系统对其进行改善.建立了磁流变半主动悬架侧倾4自由度动力学模型,基于测试数据建立了磁流变减振器的精确控制模型;根据前期提出的仿人智能控制方法,对磁流变半主动悬架系统受路面不平激励引起的侧倾进行了仿真研究;选用某型号轿车作为试验车辆,用磁流变半主动悬架替代原车被动悬架进行了实车道路试验,并将其与天棚阻尼的控制效果进行对比.仿真和道路试验结果表明,采用磁流变半主动悬架系统能够降低由于路面激励引起的侧倾振动加速度峰值,提高侧倾稳定性,仿人智能控制的效果要优于天棚阻尼控制.
英文摘要：
To overcome the poor roll stability of traditional passive suspension systems, a magneto-rheological （MR） semi-active suspension was put forward to improve it. Firstly, the four degrees of freedom roll dynamic model was constructed and an accurate model of MR damper was formulated on the basis of the tested datum. The numerical simulation of MR suspension system under rough road was then carried out using the semi-active human simulated intelligent control （HSIC） proposed in the prior study. At last, a passenger ear was selected as test car and the road test with HSIC was also carried out. As comparison, the road test of MR suspension system using skyhook damping control was also performed. The results of simulation and road test show that the MR suspension system can depress the peak values of roll angular acceleration of vehicle and improve the roll stability. Moreover, the control performance of HSIC is superior to that of skyhook damping control.
