The invention discloses a self-powered automobile suspension system capable of being actively regulated and controlled, which belongs to the technical field of automobile suspension control, has the advantages of vibration energy recovery, adjustable and controllable spring stiffness and active regulation and control of the damping coefficient of a damper, and solves the problems of a hydraulic shock absorber in the prior art. The magnetorheological fluid is used on the automobile suspension shock absorber, and meanwhile, an electromagnetic loop is designed to regulate and control a magnetic field, so that the damping can be autonomously adjusted, and a better vibration suppression effect is achieved; the piezoelectric stack is pasted along the spring wire of the suspension spring, when the piezoelectric stack is powered on, the spring rigidity can be adjusted, when the piezoelectric stack is not powered on, current can be generated at the two ends of the piezoelectric stack along with deformation of the spring, the current can be converted into electric energy to be stored, and vibration energy recovery is achieved.
本发明公开了一种可主动调控的自供能汽车悬架系统,属于汽车悬架控制技术领域,所述悬架系统具有振动能量回收、弹簧刚度可调控、阻尼器阻尼系数主动调控的优点,解决了现有技术中液压减振器存在的问题。本发明将磁流变液用作汽车悬架减振器上,同时设计电磁回路,进行磁场的调控,可实现阻尼大小的自主调节,达到更好的抑振效果;将压电堆沿悬架弹簧的簧丝进行粘贴,当向压电堆通电时,可以实现弹簧刚度的调节,当压电堆不通电时,随着弹簧的变形,会在压电堆的两端产生电流,可以转化为电能储存,实现振动能量回收。
