Shock-absorbing energy-consuming supporting seat made of shape memory alloy

Abstract

The invention belongs to the field of shock-absorbing technology researches, and specifically relates to a metal rubber shock-absorbing energy-consuming device controlled by a shape memory alloy structure in a vibration manner. The metal rubber shock-absorbing energy-consuming device consists of rubber elements, an upper layer connection steel plate, a lower layer connection steel plate, shape memory alloy wire bundles, smooth round rings and pulley wheels, the rubber elements are connected with the upper layer connection steel plate and the lower layer connection steel plate, the lower layer connection steel plate is connected with a fixed reference system, the upper layer connection steel plate is connected with a bearing object, the smooth round rings are uniformly distributed and welded on the upper layer connection steel plate and the lower layer connection steel plate and sleeved with the pulley wheels, and the shape memory alloy wire bundles and the pulley wheels are arranged on the periphery of a supporting seat through the smooth round rings. The invention combines characteristics of superelasticity and energy consumption of shape memory alloy and provides a novel shock-absorbing energy-consuming supporting seat made of the shape memory alloy. The metal rubber shock-absorbing energy-consuming device has the advantages that by means of the superelasticity and the energy consumption of the shape memory alloy, the multi-dimensional shock insulation of the structure is achieved, and shock insulation effects are improved.

Description

technical field [0001] The invention belongs to the research field of damping technology, and in particular relates to a metal rubber damping and energy-consuming device for vibration control of a shape memory alloy structure. Background technique [0002] Under the action of strong vibration, it will bring huge damage to the structure, so the study of a safer, more economical and reliable building structure isolation system has become an important topic in the field of structural earthquake resistance. Although the current rubber shock-absorbing bearing can reduce the degree of damage to the building structure to a certain extent, it still cannot meet the needs of production, so the research on a high-efficiency shock-absorbing bearing is very meaningful. [0003] Nowadays, ordinary rubber bearings are a relatively mature shock-isolation technology, which have been widely used in recent years due to their good shock-isolation effect and remarkable shock-absorbing performanc...
