摘要
采用功率流的方法,对车用电磁悬架的馈能特性进行了分析。给出了馈能式电磁悬架的能量转换量及转换率的量化方法。解决了馈能式电磁悬架系统的能量量化问题。对馈能式主动电磁悬架系统、馈能式被动电磁悬架系统和最大馈能系统的馈能特性进行了比较。结果表明所设计的馈能系统具有以下特性:馈能式电磁悬架系统各部分的能量转换量在时间域上呈现出非线性特性;馈能式被动悬架系统的馈能特性优于馈能式主动悬架系统;馈能式主动悬架系统反馈的能量大于其消耗的能量,馈能式主动悬架系统可以实现自供能。
The energy regenerative characteristic of vehicle electromagnetic suspension is analyzed based on the power flow. In order to solve the key problem of energy quantification of electromagnetic suspension,a calculation and analysis method of energy conversion efficiency is proposed. A comparative work between the active system, passive system and the maximal output power system is made through computer simulation. It is demonstrated that in the aspect of vehicle dynamics, the active system is superior to the passive system. In the aspect of energy regenerative ability, the passive system is superior to the active system. And the energy regenerated by the active system is more than the consumed energy. So the active system has the ability of powering itself.
