阻尼匹配及功率计算是制约电磁馈能悬架设计关键性问题.通过单轮二自由度行驶振动模型,利用基于舒适性和基于安全性的最佳阻尼比,建立了车辆悬架最优阻尼比数学模型.在此基础上,依据悬架功率等于原车载减振器耗散功率的原理,建立了悬架最佳功率设计数学模型.通过设计实例,对某车辆悬架的最大耗散功率和额定功率进行了设计计算,并对原车载减振器分别在最大速度和常规速度下的耗散功率进行了试验验证.试验结果分析可知,悬架最大功率和额定功率的设计值与原车载减振器特性试验的分析值相吻合,相对偏差为1.7%和1.4%,表明所建立的悬架功率设计数学模型是正确的.

Damping matching and power calculation are the key problems that restrict the electro‐magnetic energy regenerative suspension design .With single wheel two freedoms driving vibra‐tion model ,by the vehicle suspension system optimum damping ratio based on driving safety and ride comfort ,the optimal damping ratio mathematical model of vehicle suspension system was es‐tablished .According to the suspension power is equal to the original car shock absorber dissipa‐tion power ,the suspension optimal power design mathematical model was established .With an example ,we designed the maximum power and rated power of vehicle suspension ,and tested the shock absorber dissipation power under maximum speed and normal speed .The test results anal‐ysis show that the maximum power and rated power of suspension are accordance with the exper‐imental values of the original car shock absorber ,and the relative deviation is 1 .7% and 1 .4% . This indicates that the established suspension power design mathematical model is correct .
