摘要: 应用Bingham本构力学模型,分析得到磁流变阻尼器(MRD)的6个主要参数与输出阻尼力F的关系。利用得到的力学模型分析MRD的6个参数对输出阻尼力F和动态范围λ的影响。建立基于MRD的1/4车辆悬架系统模型,分析MRD被动阻尼系数cs对车辆悬架减振效果的影响。提出一种百分比斜率均方根值作为参数影响程度的评价方法,分析得到MRD的6个参数对车辆悬架减振效果的影响规律,同时考虑分析MRD磨损对车辆悬架减振效果的影响。结果表明:活塞直径d2和缸体内径D对减振效果的影响较大,其它参数对减振效果的影响则较小。当动态范围λ和输出阻尼力F都足够大时,车辆悬架能够获得较好的减振效果。Abstract: The relationships among of damping force F and six main parameters of magnetorheological damper (MRD) were obtained based on the Bingham constitutive model. The effects of the six parameters on the damping force F and dynamic range λ were also discussed. At the same time, a quarter vehicle suspension model with MRD was established. Based on the Bingham constitutive model, the influence of the passive damping coefficient cs of MRD on the damping effect of vehicle suspension was analyzed. Moreover, the RMS value of the percentage-based slope was put forward to evaluate the influence degree of the six parameters of MRD on the vibration attenuation effect, and the influence of damper wear on the damping effect was also obtained. The results show that the piston diameter d2 and cylinder inner diameter D have a great influence on the damping effect, and other parameters have little influence on the damping effect. It also identified that when the dynamic range λ and damping force F are all large enough, the vehicle suspension can get better damping effect.
