Problems solved by technology

[0004] Vibration damping pads are mainly used in places that require sound insulation and vibration reduction, and have excellent damping and vibration reduction effects. Therefore, they are widely used in various industries. Most of the vibration damping pads currently used are ring-shaped rubber materials. Vibration damping pad, this kind of vibration damping pad has a simple structure, but the effect of sound insulation and vibration reduction is average

Abstract

The invention discloses a memory alloy damper. The memory alloy damper comprises a damper body. The damper body is of a three-dimensional net rack structure which is formed by winding at least one memory alloy wire. The memory alloy damper has superelasticity and good damping performance, is resistant to abrasion, corrosion, high-low temperatures and vacuum and suitable for different environments, and can effectively reduce various vibrations, prevent looseness, reduce noise, prolong the service life of equipment and improve the equipment safety.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a memory alloy shock absorber and a preparation method thereof. Background technique [0002] Vibration is a kind of periodic reciprocating motion. Any kind of machinery will vibrate, and the main causes of mechanical vibration are the unbalance of rotating or reciprocating parts, the unbalance of magnetic force and the mutual collision of parts. At present, the international community has listed vibration as one of the seven major environmental hazards, and has begun to study the impact of vibration pollution and human activities on the ground, buildings, traffic vehicles and other vibrations on people's living and working environments, and on human health. The impact on the safety of buildings and the normal use of precision instruments. [0003] With the development of modern industry, the types and quantities of large-scale machinery that generate strong vibrations are increas...
