The invention discloses an inerter-combined high-static low-dynamic-stiffness automobile passive seat suspension system, which comprises an inerter element, the upper end of the inerter element is connected to the bottom of an automobile seat, the lower end of the inerter element is connected to the bottom of an outer frame, and the inerter element is used for reducing the inherent frequency of the system and enhancing the low-frequency vibration isolation performance; the upper end of the damper is connected to the bottom of the automobile seat, the lower end of the damper is connected to the bottom of the outer frame, and energy, mainly heat energy, generated in the movement process of the seat can be absorbed; a high-static and low-dynamic stiffness mechanism generates a negative stiffness effect, reduces the inherent frequency of the system and strengthens the low-frequency vibration isolation performance by using a horizontally arranged spring, a sliding block, a hinge and a connecting rod, and meanwhile, ensures the static load capacity of a seat suspension system and reduces the static displacement of a seat through a vertically arranged spring. According to the invention, the problem that a traditional linear suspension system loses consideration in low-frequency vibration isolation and static load capacity is solved, and the riding comfort can be obviously improved.

    本发明公开了一个结合惯容的高静低动刚度汽车被动座椅悬架系统,该悬架系统包括一个惯容元件,上端连接在汽车座椅底部,下端连接在外框底部,用于减小系统的固有频率,加强低频隔振性能;一个阻尼器,上端连接在汽车座椅底部,下端连接在外框底部,能够吸收座椅运动过程中产生能量,主要是热能;一个高静低动刚度机构,利用水平布置的弹簧、滑块、铰链和连杆,产生负刚度效应,减小系统的固有频率,加强低频隔振性能,同时通过垂直布置的弹簧保证座椅悬架系统的静载荷能力,减小座椅静位移。本发明解决了传统线性悬架系统在低频隔振和静载荷能力中顾此失彼的问题,能够显著提升乘坐舒适度。
