摘要
采用轮毂电机驱动的车辆非簧载质量显著增大,并且路面激励直接作用在电机上,影响电机的电磁效应,使得振动加剧,因此提出一种新型动力吸振构型.将电机作为吸振器悬置在车轮之内,并针对此构型提出一种新的半主动悬架混合控制策略,且通过Matlab建模仿真.结果表明簧上加速度和轮胎动挠度均有所衰减,采用混合控制策略的悬架系统在平顺性方面有所提升.
The fact that vehicle unsprung mass driven by in-wheel motors is significantly increased,and the road surface excitation acts on the motor directly, will affect the electromagnetic effect of the motor,making the vibration intensified. Therefore, a new type of dynamic vibration-absorbing structure is proposed. The motor is suspended in the wheel as a vibration absorber, and a new semi-active suspension hybrid control strategy is proposed for this configuration. Through Matlab modeling and simulation, the results show that both the sprung acceleration and the tire dynamic deflection are attenuated, and the suspension system with hybrid control strategy has improved in terms of ride comfort.
