为解决非簧载质量增加导致电动轮驱动电动汽车平顺性下降问题,提出了一种集成了磁流变半主动悬架的多功能电动轮系统,对其关键组成部分—轮内磁流变减振器进行了结构设计和关键参数的计算,建立了混合工作模式下的磁流变减振器数学模型,并进行了仿真分析,分析结果表明减振器结构紧凑,可以实现阻尼力的连续可调,能够满足电动轮车的减振要求,为改善电动轮车的平顺性提供了一种有效可行的新型阻尼装置,有利于下一步进行轮内磁流变减振器的制作和试验研究。
In order to solve the problem of ride comfort deterioration as a result of un-sprung mass increase of the motorized wheel driven electric vehicle, a new multifunctional motorized wheel driving system including magneto-rheological semi- active suspen, ion was proposed.As the key component of motorized wheel system, magneto rheologieal damper (MRD) was designed, and the mathematical model of MRD under the mixed working mode was estlished, then the simulation analysis was carried on. The analysis results show that the MRD has the advantage of compact structure, and it can meet the requirements of engineering. It provides a new effective and feasible damping device improving the ride comfort of the motorized wheel driven electric vehicle, and is beneficial to the manufacture and test research for in-wheel MRD next.
