The invention relates to a shear thickening liquid impact-resistant damper which solves the problems that the prior damper adopting hydraulic oil has dissatisfactory effects of oscillation damping and restoring. The damper comprises a cylinder body and a piston; the diameter of the piston is less than or equal to the inside diameter of the cylinder body; more than one piston is arranged on a piston rod coaxially and alternately; the cylinder body corresponding to the piston is inside provided with a movable piston; a cavity body of one side of the movable piston corresponding to the piston isa working cavity; the cavity body of the other side of the movable piston is a bottom cavity; the working cavity is inside provided with shear thickening liquid; the cylinder body of the upside of the shear thickening liquid is inside provided with working gas or without working gas; the bottom cavity is inside provided with high-pressure gas. The invention adopts the shear thickening liquid in order that the damping force produced by the impact-resistant damper greatly satisfies the needs of impact resistance and oscillation damping, has wide application range and can be suitable for variousworking conditions; as the shear thickening liquid has the shear thickening property, the piston of the damper need not be in fit with the cylinder body and reduces the processing requirements of thepiston and cylinder body, thereby reducing the production cost.
