The invention belongs to the field of vehicle protection, and particularly relates to a spinning friction type vehicle lightning protection seat installation energy absorption device. The device is arranged between a seat and the bottom of a vehicle and comprises a connection guide mechanism, a spinning mechanism and a composite multi-field coupling energy absorption mechanism, and the connection guide mechanism is used for achieving connection between the seat and an energy absorption buffer device, decoupling with a vehicle body during impact and guiding the seat to move; the spinning mechanism is used for generating rotary compression motion when being impacted and is connected with the vehicle body, and axial impact is converted into spiral motion; when a vehicle is impacted, the combined type multi-field coupling energy absorption mechanism achieves buffering and energy absorption on impact through cooperation of multiple physical fields of torsion-compression coupling plastic deformation, compression plastic deformation and friction-viscous damping coupling. The invention provides an energy absorption device which is compact in structure, high in efficiency and high in stability, impact on passengers during explosion can be greatly reduced, and the injury risk of the passengers is reduced.

    本发明属于车辆防护领域,具体涉及一种旋压摩擦式车辆防雷座椅安装吸能装置。设置在座椅和车辆底部之间,包括连接导向机构、旋压机构和复合式多场耦合吸能机构,其中连接导向机构用于实现座椅和吸能缓冲装置的连接以及冲击时与车体解耦并引导座椅运动;旋压机构用于受到冲击时产生旋转压缩运动并连接车体,将轴向的冲击转化为螺旋运动;当车辆受到冲击时,复合式多场耦合吸能机构通过扭转‑压缩耦合塑性变形、压缩塑性变形以及摩擦‑粘滞阻尼耦合的多物理场协同实现对冲击的缓冲和吸能。本发明提供一个结构紧凑,具有高效率、高稳定性的能量吸收装置,能够大幅削减爆炸时对乘员的冲击,降低乘员损伤风险。
