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.
