摘　　要：设计了一种基于多自由度球形电机的新型磁流变悬架,以把此类电机在应用汽车上。对磁流变悬架主要结构进行设计,并采用ANSYS软件,分析悬架静强度,仿真阻尼器磁路磁场,获取悬架的应力云图以及阻尼器磁感应强度云图,建立二自由度动力学仿真模型,仿真平顺性。结果表明:在最大制动力工况、最大垂直力工况以及最大侧向力工况3种工况下,悬架所受最大应力均不超过355 MPa的材料许用应力。车身加速度为0.23 m/s^(2),轮胎最大动载荷为2 kN,悬架最大动挠度小于50 mm。因此,结构设计满足静强度需求;悬架的平顺性达到设计预期。A new type of magnetorheological suspension was designed based on a multi-degree-offreedom spherical-motor to apply this kind of motor in automobile.The main structure was designed of the magnetorheological suspension with analyzing the static strength of the suspension and magnetic field simulation of the damper using ANSYS software.Obtained a stress nephograph of the suspension and the magnetic induction intensity nephograph of the damper;Established a two-degree-of-freedom dynamic model to simulate ride comfort.The results show that the suspension maximum stress under three working conditions,including the maximum braking force,the maximum vertical force,and the maximum lateral force,does not exceed the material allowable stress of 355 MPa.The vehicle body acceleration is 0.23 m/s^(2);The tire maximum dynamic load is 2 kN;The suspension maximum dynamic deflection is less than 50 mm.Therefore,the structural design meets both the static strength requirements and the expected suspension ride comfort.
