A composite buffer energy-absorbing device based on magnetorheological fluid

Abstract

The patent of the present invention discloses a composite buffer energy-absorbing device based on magnetorheological fluid. Nut (5), M8 slotted screw (6), No. 1 magneto-rheological fluid buffer (7), small steel ball (8), collision energy-absorbing cavity (9), No. 1 buffer spring (10), spring Connecting plate (11), No. 2 magnetorheological fluid buffer (12), right-angle fixing block (13), M30 bolt (14), No. 3 magnetorheological fluid buffer (15), No. 2 buffer spring (16) , piston valve (17), air compensation cavity (18), buffer outer cylinder (19), sealing ring (20), excitation coil (21), magnetorheological fluid (22). The composite buffer energy-absorbing device combines the magnetorheological buffer and the multi-particle collision energy-absorbing device, and can adjust the damping force of the buffer device in real time according to the magnitude of the external impact force, so as to achieve the optimal buffering and energy-absorbing effect.

Description

technical field [0001] The invention belongs to the technical field of buffer energy absorption and relates to a composite buffer energy absorption device based on magnetorheological fluid. Background technique [0002] As one of the main forms of motion, impact is a phenomenon that exists widely in nature. The purpose of studying impact is to reduce its harmful effects. As engineering equipment develops towards high-speed and heavy-loading, the impact intensity encountered is also increasing. , solving the problem of impact buffering is crucial to improving engineering quality. Shock refers to the movement of the system under transient excitation. It is characterized by the fact that the action time of the excitation is much shorter than the movement period of the system, and it belongs to a sudden and violent movement. The traditional buffer energy-absorbing device is mainly made of materials such as rubber or spring. The main advantages of this type of buffer device are ...

AI Technical Summary

Problems solved by technology

The traditional buffer energy-absorbing device is mainly made of materials such as rubber or spring. The main advantages of this type of buffer device are simple structure and low cost; however, this type of buffer device can only be used for the impact of specific loads, especially in places with high requirements. Occasionally, the buffering effect will be unsatisfactory, and the application range will be greatly limited.
