带主动横向稳定杆的混合电磁悬架性能研究

Study on Performance of Hybrid Electromagnetic Suspension with Active Roll Stabilizer

为了提高半主动混合电磁悬架抗侧倾性能,将主动横向稳定杆与其进行集成。在Adams/Car中建立了带主动横向稳定杆及混合电磁悬架的整车底盘模型,并在Simulink中建立了混合电磁悬架的改进天棚控制策略以及主动横向稳定杆的模糊比例控制策略,通过所设计的模糊规则可以使得主动横向稳定杆的刚度在不同工况下与混合电磁悬架性能要求相匹配。联合仿真结果表明:带有主动横向稳定杆的半主动混合电磁悬架在匀速直线行驶时,能够更好地提高乘坐舒适性以及振动能量回收性能,在转向或侧倾角过大时,能够更快地调整车身姿态以提高操稳性。

In order to improve the anti-roll performance of semi-active hybrid electromagnetic suspension,the active roll stabilizer was integrated with it.The vehicle chassis model equipped with hybrid electromagnetic suspension and active roll stabilizer was built in Adams/Car.Modified skyhook control strategy of hybrid electromagnetic suspension and fuzzy-p control strategy of active roll stabilizer was designed in Simulink.By designing fuzzy rules,the stiffness of the active roll stabilizer can be matched with the performance requirements of the hybrid electromagnetic suspension under different working conditions.The co-simulation results show that the semi-active hybrid electromagnetic suspension with active roll stabilizer can improve ride comfort and regenerative capacity when it is running in a uniform straight line,and it can adjust body attitude faster to improve the handling and stability when it is turning or roll is too large.
