摘要
车辆悬架是车辆行驶系统的重要组成之一,主要功能是承受车身的重量和减少来自路面的激励,其性能的好坏直接影响到乘用车的乘坐舒适性,并且间接影响到车辆行驶的安全性和操纵稳定性。传统的被动悬架结构参数固定,减振效果受到限制,半主动悬架可以通过控制算法改变悬架的阻尼和刚度,可以达到和主动悬架一样的控制效果,结构相比于主动悬架更为简单且成本更低。空气弹簧和磁流变阻尼器(MRD)可以分别改变磁流变半主动空气悬架的刚度和阻尼,是半主动悬架减振的重要研究对象。该文在介绍磁流变半主动空气悬架的工作原理及单一控制策略的基础上,结合国内外最新的研究成果,重点综述磁流变半主动空气悬架的复合控制策略,最后探讨磁流变半主动空气悬架的发展趋势以及面临的问题,为磁流变半主动空气悬架的技术发展作进一步参考。
Vehicle suspension is one of the important components of the vehicle driving system,mainly for bearing the weight of the body and reducing the excitation from the road surface,whose performance directly affects the safety and handling stability of the vehicle.It also has a great impact on the riding comfort of the occupants.The traditional passive suspension structure parameters are fixed,the vibration damping effect is limited,and the semi-active suspension can change the damping and stiffness of the suspension through the control algorithm,which can achieve the same control effect as the active suspension,and the structure is simpler and lower in cost than the active suspension.Air springs and magnetorheological dampers can change the stiffness and damping of semi-active suspension,respectively,and are important for semi-active suspension damping.On the basis of introducing the working principle and single control strategy of magnetorheological semi-active air suspension,this paper focuses on the composite control strategy of magnetorheological semi-active air suspension,and finally discusses the development trend and problems of magnetorheological semi-active air suspension,so as to provide further reference for the technical development of magnetorheological semi-active air suspension.
