摘要
针对商用车质量大、重心高易发生侧翻的问题,提出了一种由倾斜布置的电控悬架系统和主动连杆滑块机构组成的新型电控悬架。介绍了这种悬架的结构设计方案和工作原理,利用ADAMS软件建立了该悬架动力学模型并进行了仿真研究。结果表明:在汽车发生侧倾运动时,通过调整悬架弹簧刚度、减振器阻尼以及作动器作用力的大小,可以减小簧载质量侧倾角,降低车轮横向载荷转移率,提高商用车的抗侧翻能力。仿真获得的组合控制各项目标参数与汽车侧向加速度输入间的关系,为该新型电控悬架进一步设计和控制策略的编写提供了理论参考。
Aiming at the rollover problem of the commercial vehicle with large mass and high center of gravity,a new type of electronically controlled suspension is proposed,which is composed of a tilted arrangement of an electronically controlled suspension system and an active link and slider mechanism.The structure design scheme and working principle of the suspension are introduced.The dynamics model of the suspension is established by ADAMS software and the simulation research is carried out.The results show that when the car is rolling,by adjusting the stiffness of the suspension spring,the shock absorber damping and the actuator force,the sprung mass roll angle can be reduced,the lateral load transfer rate of the wheel can be reduced,and the property of the commercial vehicle to prevent rollover can be improved.The combination of simulation obtained by controlling each target parameter and the input of lateral acceleration of the vehicle provides a theoretical reference for the further design of the new electronically controlled suspension and the development of control strategies.
