Abstract: Disclosed are a compound impact-resistant device and an application thereof. The compound impact-resistant device includes an inner cylinder, a first pressure sensor and an outer cylinder; an inner cavity of the inner cylinder is connected to a magnetorheological damper, a spiral valve element, a floating piston and a spring from bottom to top; and the outer cylinder is connected to a piston rod, a bottom end of the piston rod penetrates a top of the inner cylinder, the spring and the floating piston to be connected to the spiral valve element, and a portion below the spiral valve element is filled with hydraulic oil. The compound impact-resistant device can provide specific initial support force and achieve active self-adaptation to dynamic impact, thus solving the problems that traditional hydraulic buffers cannot provide initial support force and traditional mechanical crushing members have difficulty in providing large support force.
