【摘要】 建立车辆半主动悬架1/4模型,提出可调减振器阻尼控制的实现方法,设计半主动悬架台架试验系统。在可调减振器试验的基础上,建立了可调减振器阻尼与步进电机转角之间的关系。最后,对半主动悬架1/4物理模型进行了台架试验。结果表明,试验系统稳定可靠,阻尼控制易于实现,半主动悬架能较好地适应不同的路面输入,为半主动悬架及控制系统的进一步研究奠定了基础。更多还原

【Abstract】 The paper presents quarter model of semiactive suspension is established,the method of implementing damping control is presented,and the indoor quarter model test system design.Based on the test of turnable damper,the relation between damping of the damper and angle of stepelectromotor is developed.Then, the bench test of indoor quarter semiactcive suspension is done.The result shows that the test system is stable and reliable,the damping control is easy to implement,semiactive suspension is easy to fit different road input,which provides the basis for further study of semiactive suspension and control system.更多还原
