摘　　要：针对电动轮汽车与传统悬架结构配合存在干涉、占用空间大等问题,提出了一种集成于电动轮轮辋内、对置布置双磁流变减振器的悬架结构。分析电动轮轮辋空间及该悬架结构连接关系,设计磁流变减振器、悬架弹簧的基础上,建立了磁流变减振器Bingham仿真模型,分析磁流变减振器力学特性,结果表明:磁流变减振器响应速度快、输出阻尼力连续可调,满足电动轮汽车对减振性能的要求;对悬架弹簧根据最大剪应力理论进行校核,并进行有限元分析,结果误差小于0.5%,且均未超过材料许用极限,满足强度要求,悬架弹簧安全可靠。The cooperation between motorized wheel vehicle and traditional suspension structure has some problems,such as interference of components and occupy large space.Therefore,the opposed 2 magneto-rheological(MR)dampers suspension integrated in the motorized wheel is presented.Based on the analysis of the connection relationship between the rim space of the motorized wheel and the components of the suspension,MR damper and suspension spring are designed.The Bingham model of MR damper is established and the properties are analyzed.Results show that MR damper has fast response speed and continuous adjustable output force,can meet the requirement of motorized wheel vehicle.The maximum shear stress theory and finite element analysis of the suspension spring are carried out.The error of the results is less than 0.5%,neither of which exceeds the allowable limit of material,meets the strength requirement,it’s safe and reliable.
