【摘要】 文中对适用于车辆半主动悬架控制器设计的磁流变阻尼器模型进行研究。首先分析阻尼力与位移、速度以及输入电流之间的关系,并结合现有阻尼器模型的优点,提出一种精确的便于控制的双曲正切磁滞模型。接着,将磁流变阻尼器安装在硬件在环仿真平台上进行试验,利用试验得到的阻尼器动态特性数据,进行阻尼器模型的参数辨识和曲线拟合。最后,将基于拟合参数的模型仿真结果与试验数据进行比较,验证了模型的正确性。更多还原

【Abstract】 A magneto-rheological(MR) damper model suitable for the design of vehicle semi-active suspension controller is studied in this paper.Firstly,the relationships between damping force and displacement,velocity and input current are analyzed,and combining with the advantages of existing damper models,an accurate and easy-to-control hyperbolic-tangent hysteresis model is proposed.Then,an MR damper is mounted on a hardware-in-the-loop platform for test,and by using the dynamic characteristic data of damper obtained from the test,parameter identification and curve fitting for damper model are conducted.Finally,the proposed MR damper model is verified by comparing the model simulation curves(based on fitted parameters) with the experimental ones.更多还原
