摘　　要：针对传统被动悬架无法将振动产生的能量充分利用的问题,提出了一种直线电机式馈能悬架,并探究了该悬架的馈能特性.建立1/4车动力学模型,以正弦路面作为输入激励推导出影响馈能的悬架系统参数;以感应电动势为指标,基于直线电机式馈能悬架模型,采用控制变量法对悬架系统参数进行仿真分析;通过搭建的1/4车悬架实验平台进行实验验证.结果表明,簧载质量、非簧载质量和弹簧刚度与直线电机产生的感应电动势呈负相关,轮胎刚度与直线电机产生的感应电动势呈正相关.Aiming at the problem that conventional passive suspensions cannot utilize the energy of vibration,a linear motor type energy-harvesting suspension was proposed,and the energy-harvesting characteristics of the suspension were discussed.The quarter-vehicle dynamic model was established,and the suspension parameters influencing energy-harvesting characteristics were derived under sine excitation.Through taking the induction electromotive force as the index and based on the model for the linear motor type energy-harvesting suspension,the suspension parameters were simulated and analyzed with a control variate method.In addition,an experiment was conducted using by a quarter-vehicle suspension experimental platform.The results show that the sprung mass,unsprung mass and spring stiffness are negatively correlated with the induced electromotive force of the linear motor,and the tire stiffness is positively correlated with the induced electromotive force of the linear motor.
