Impact load self-adaptive buffer device

Abstract

The invention relates to a hydraulic variable-damping self-adaptive buffer device, in particular to an impact load self-adaptive buffer device. The device comprises an air storage barrel and a bufferbarrel. The air storage barrel is arranged in the buffer barrel in a sealed mode, a piston is arranged in the air storage barrel, a cavity I is formed by one side of the piston and the air storage barrel, a piston rod is arranged on the other side of the piston, and one end of the piston rod stretches out of the air storage barrel. A floating piston is arranged between the air storage barrel and the buffer barrel, the floating piston divides a cavity between the air storage barrel and the buffer barrel into a cavity II and a cavity III, a buffer valve and a rest valve are arranged between theair storage barrel and the buffer barrel, the opening of the buffer valve is adjusted through a buffer valve adjusting device, the opening of the reset valve is adjusted through a reset valve adjusting device, the buffer valve and the reset valve are communicated with the cavity I respectively, a liquid injection device communicated with the exterior is arranged on the cavity I, the cavity II is communicated with a liquid flow hole in the buffer valve, a small liquid flow hole is formed between the cavity II and the cavity I, and an air injection device communicated with the cavity III is arranged on the buffer barrel.

Description

technical field [0001] The invention relates to a hydraulic variable damping adaptive buffer device, in particular to an impact load adaptive buffer device. Background technique [0002] With the rapid development of industrial technology, transportation vehicles such as automobiles and airplanes, and power machinery such as space shuttle launchers, weapon launchers, and motors are all developing in the direction of high speed and heavy load. The problem of shock vibration has been increasingly valued by designers. Under the action of high-speed and heavy-duty transient loads, the frame and carrier must bear a large impact load, which often leads to heavy equipment, poor mobility and stability, and affects the life of the equipment and the human-machine environment. For a long time, in order to effectively overcome the adverse effects caused by transient shock vibrations, passive, active and semi-active buffer devices have been proposed successively. The buffer device is a ...

AI Technical Summary

Problems solved by technology

At present, the size of the flow hole of the commonly used hydraulic buffer is generally fixed, and the size of the flow hole cannot be adjusted during the working process. Therefore, a large resistance peak often appears at the beginning of the buffer, and in the The resistance provided in the later stage is often too small, resulting in relatively large vibration
