摘　　要：为协调线性电磁主动悬架在提高系统动力学性能与降低系统能耗间的矛盾关系,以混合电磁主动悬架为潜在解决方案.基于改进天棚控制策略,得到了混合电磁主动悬架相较于线性电磁主动悬架能够实现节能的一般性机理.以被动悬架和线性电磁主动悬架为研究对象,进行了动力学性能与节能性能的对比台架试验,结果表明:相较于被动悬架,混合电磁主动悬架在确保车轮与地面具有良好接触的前提下,车身加速度和悬架动挠度均方根值分别降低了23.35%和14.97%;相较于线性电磁主动悬架,在获得相同动力学控制效果的前提下,混合电磁主动悬架消耗的电功率降低了70.60%,验证了混合电磁主动悬架在兼顾系统动力学性能与系统能耗方面的优越性.To coordinate the contradiction between improving the dynamic performance and reducing the energy consumption of the system,the hybrid electromagnetic active suspension(HEMAS)was used as a potential solution.Based on the improved skyhook control strategy,the general energy-saving mechanism of HEMAS was realized compared with linear electromagnetic active suspension(LEMAS).Taking the passive suspension and the LEMAS as comparison objects,a comparison bench test was carried out.The test results show that compared with passive suspension,the RMS of vehicle acceleration and suspension dynamic deflection of the HEMAS are respectively reduced by 23.35%and 14.97%with good tire grounding ability.Compared with LEMAS,the electric power consumption of the HEMAS is reduced by 70.60%for the same dynamic performance,which verifies the superiority of HEMAS with consideration of the system dynamic performance and energy consumption.
