The invention relates to a membrane-type amplitude-correlation vibration reduction device. According to the membrane-type amplitude-correlation vibration reduction device, the damping characteristics can be changed along with stimulation amplitudes. The vibration reduction device comprises a working cylinder, a piston assembly and a limiting block, wherein the piston assembly and the limiting block are arranged in the working cylinder. The vibration reduction device is characterized by further comprising a membrane-type amplitude-correlation assembly E connected with the piston assembly; the membrane-type amplitude-correlation assembly E is formed by an elastic membrane, a piston rod, an expiration and inspiration cavity, an upper end cover and a lower end cover, the upper end cover, the lower end cover and shaft shoulders of the piston rod are fixed, the elastic membrane is arranged outside the piston rod in a sleeving mode through the upper end cover and the lower end cover, the expiration and inspiration cavity is arranged outside the elastic membrane in a sleeving mode through the upper end cover and the lower end cover, and the limiting block is arranged on the piston rod. When a vehicle runs on a good road, the vibration reduction device can provide small damping, and the good taking comfort can be guaranteed; when the vehicle is steered or runs on a bumping road, the vibration reduction device can provide large damping, and the good control stability and the good running safety can be guaranteed.
