摘要
根据牛顿流体模型和滨汉塑性流体模型 ,分别对混合工作模式的汽车磁流变减振器进行了理论分析研究。按照长安微型汽车的技术要求 ,设计和制作了汽车磁流变减振器 ,并对此进行了试验测试。试验结果表明 ,应用所提出的理论分析模型是可行的 ,对设计特殊阻尼特性的磁流变减振器有一定的指导意义。
A magnetorheological fluid (MR fluid)shock absorber model is analyzed theoretically using Newtonain fluid and idealized nonlinear Bingham plastic model respectively for the mixed mode of flow mode and shear mode In the light of the technician requirements for Changan mini-automobile, a MR fluid shock absorber is designed and fabricated using commercial MR fluid The nonlinear MR fluid shock absorber model is validated experimentally The results reveal that the shock absorber model is reasonable and the MR fluid shock absorber for a specific application can be designed according to the MR fluid shock absorber model presented
