摘要
为了协调馈能悬架减振性能和馈能性能,提高馈能效率,提出了一种电磁复合式馈能悬架结构形式,建立了电磁复合式馈能悬架数学模型,并加以试验验证。设计了功率模块电路和新型模式切换控制策略,并进行了对比仿真分析。研究结果表明,该悬架系统的动态特性下降了4%左右,但是馈能效率提高了13.65%,说明该电磁复合式馈能悬架在保证悬架性能的条件下,有效提高了馈能效率。
To coordinate the damping performance and energy regenerative performance of the energy-regenerative suspension and increase the energy recovery efficiency, an energy-regenerative suspension system with electro-magnetic hybrid actuator was put forward. The mathematical model of the energy-regenerative suspension with electro-magnetic hybrid actuator was established and verified by experiments. The power module circuit and the new mode switching control strategy were designed, and corresponding numerical simulation was carried out for comparison and analysis. The results show that the dynamic performances of energy-regenerative suspension drops by about 4%, while the energy recovery efficiency increases by 13.65%, which means that the energy recovery efficiency of the electro-magnetic hybrid energy-regenerative suspension can be effectively improved when the requirements of certain vehicle ride comfort are satisfied.
