The invention discloses a variable stiffness inertial load reduction device based on dry adhesion characteristics, which comprises a plurality of variable stiffness mechanisms for connecting a helmet and clothes and a connecting structure detachably connected with the helmet and the clothes, comprising an upper mechanism with a high-rigidity outer sleeve and a lower mechanism with a low-rigidity air-driven expansion inner sleeve, the upper mechanism is detachably connected with a helmet through a connecting structure, the lower mechanism is detachably connected with clothes through a connecting structure, and the upper mechanism is connected with the lower mechanism in a sleeving mode; an air bag of the lower mechanism is inflated to expand, so that an inner sleeve of the lower mechanism deforms, a bionic adhesive material layer fixed on the outer surface of the inner sleeve is in close contact with the inner wall of a high-rigidity outer sleeve of the upper mechanism, and the variable-rigidity mechanism is in a high-rigidity state to realize load reduction; after the air pressure of the airbag is reduced, the lower mechanism is separated from the upper mechanism, and the variable-rigidity mechanism is in a low-rigidity state. The device is a protective device for actively reducing the inertial load, has a better inertial load reducing effect, and can not influence the relative movement of the lower mechanism and the upper mechanism at all.
本发明公开了一种基于干黏附特性的变刚度惯性载荷消减装置,包括若干连接头盔与衣服的变刚度机构和与头盔以及衣服可拆卸连接的连接结构,变刚度机构为气动执行机构,包括具有高刚度外套的上机构和具有低刚度气驱膨胀内套的下机构,上机构与头盔和下机构与衣服分别通过连接结构可拆卸连接,上机构套接下机构;下机构气囊充气膨胀,使下机构内套形变,固定在内套外表面的仿生黏附材料层与上机构高刚度外套内壁紧密接触,变刚度机构处于高刚度状态,实现载荷消减;气囊气压降低后,下机构和上机构脱离,变刚度机构处于低刚度状态。本发明是主动式消减惯性载荷的防护装置,具有更好的消减惯性载荷的效果,且可以完全不影响下机构和上机构的相对运动。
