摘　　要：根据作者新近提出的一种通用不对称滞环特性模型 ,本文对磁流液 (MR)阻尼器在汽车减振应用进行了半主动控制研究 .将所提出的MR阻尼器不对称滞环模型应用在二自由度“四分之一”汽车模型 ,并用“空挂”控制律来实现对MR阻尼器阻尼力的自动调节 .仿真结果验证了阻尼力不对称性和滞环特性对汽车悬挂性能的影响 ,且表明所设计的半主动非线性控制器的复杂性大大减化 。On the basis of the generalized asymmetric hysteresis model which has recently been proposed by the authors, this paper deals with semi-active control for the vehicle suspension vibration attenuation by employing a semi-actively controllable magneto-rheological (MR) fluid damper. The proposed asymmetric model of an MR-damper is employed in a 2-DOF 'quarter-car' model, and the 'skyhook' control law is applied to implement variable damping deduced from the MR-damper. The simulation results demonstrate the contributions of damping asymmetry and hysteresis in response to the semi-active suspension,and suggest that the semi-active nonlinear controller synthesis can be greatly simplified to achieve superior vibration attenuation performance of the vehicle suspension.
