Abstract

The invention discloses a combined buffering and energy absorption device based on magnetorheological fluid. The device is composed of a base (1), an outer sleeve (2), a stress plate (3), a M2O hexagon bolt (4), a M20 hexagon nut (5), M8 slotted screws (6), a first magnetorheological fluid buffer (7), small steel balls (8), a colliding energy absorption cavity (9), a first buffering spring (10), aspring connecting plate (11), a second magnetorheological fluid buffer (12), a right-angled fixing block (13), a M30 bolt (14), a third magnetorheological fluid buffer (15), a second buffering spring(16), a piston valve (17), an air compensator (18), a buffer outer sleeve (19), a sealing ring (20), a magnet exciting coil (21) and the magnetorheological fluid (22). According to the combined buffering and energy absorption device, the magneto-rheological buffers are combined with multiple particle colliding energy absorption devices, and the damping force of a buffering device can be adjustedin real time according to external impact force to achieve the optimal buffering and energy absorption 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 ...

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.
