Tension type magneto-rheological buffer,

Abstract

The invention provides a tension type magneto-rheological buffer, which comprises a working cylinder I, a piston I and a piston rod, wherein the piston I is arranged in the working cylinder I to separate the working cylinder I into a chamber I and a chamber II, the chamber I and the chamber II are respectively filled with a magneto-rheological material, one end of the piston rod is fixedly arranged on the piston I, the other end of the piston rod penetrates through the chamber II and extends out of the working cylinder I, and the piston I is provided with excitation coils and multiple stages of radial damping passages. When the working cylinder I is subjected to shock, the magneto-rheological material in the chamber II flows into the chamber I through the multiple stages of radial damping passages. Because the piston is provided with the multiple stages of radial damping passages, the effective lengths of the damping passages can be effectively increased when the tension type magneto-rheological buffer is subjected to shock, a larger damping force is outputted, and the buffer requirements during high-speed shock are met.

Description

technical field [0001] The invention relates to the technical field of buffering, in particular to a stretched magneto-rheological buffer that can be used in vehicles, aerospace, heavy machinery, weapons and the like. Background technique [0002] Cushioning refers to the process of alleviating the mechanical vibration of vehicles, aerospace equipment, heavy machinery or weapons when they are subjected to high-speed impact, so that the force is gentle. In practice, there are various impact situations, such as: aircraft landing, gun firing, elevator falling, machine tool parts fast reciprocating movement, etc. These impact situations will cause great impact on mechanical equipment, and the parts of mechanical equipment It will generate a lot of dynamic stress, and may even directly cause damage to parts. Therefore, it is necessary to take buffer measures when the mechanical equipment is impacted. In the prior art, the magnetorheological fluid buffer is a new type of intellig...

AI Technical Summary

Problems solved by technology

However, in the existing magneto-rheological fluid buffers, the damping channel is arranged at the gap between the working cylinder and the piston, and it is in the form of a straight line. The effective length of the damping channel formed by it is very short, and the output damping force is very small. The adjustment range is not large, it is difficult to meet the cushioning requirements under high-speed impact
