Wide-frequency high-damping vibration isolator

Abstract

The invention provides a wide-frequency high-damping vibration isolator, and belongs to the technical field of vibration noise control. The vibration isolator comprises supporting combined beams, connecting bosses, an upper equilateral triangle connecting plate and a lower equilateral triangle connecting plate, wherein the supporting combined beams are formed by bonding metal gaskets, flexible material gaskets and metal thin-wall beams through bonding agents. The three supporting combined beams are symmetrically arranged on the outer sides of the upper equilateral triangle connecting plate andlower equilateral triangle connecting plate through the connecting bosses in parallel. The connecting bosses are fixedly connected with the equilateral triangle connecting plates by screws. The movement direction of the upper equilateral triangle connecting plate is consistent with the length direction of the supporting combined beams and is perpendicular to the bending direction of the supporting combined beams. Force is transmitted to the upper equilateral triangle connecting plate after a vibration control object moves. Wide-frequency high-damping dynamic vibration reduction can be realized by the bending energy consumption of the supporting combined beams. The wide-frequency high-damping vibration isolator is large in bearing force, high in damping, capable of isolating vibration andeffectively reducing the amplitude, stable in vibration isolation, high in reliability, simple in structure and convenient to install and does not need extra energy.

Description

technical field [0001] The invention relates to the technical field of vibration and noise control, in particular to a broadband high-damping vibration isolator. Background technique [0002] With the rapid development of engineering science and technology, machining precision is getting higher and higher. Precision instruments and equipment are extremely sensitive to environmental vibrations. Small vibrations may seriously affect processing accuracy and measurement accuracy, and even cause damage to the precision equipment itself. Long-term vibrations can easily cause resonance of various parts and cause screws or nuts to fall off. Therefore, high-efficiency vibration isolators must be used to isolate environmental vibrations in order to obtain good processing accuracy and protect precision instruments.

Problems solved by technology

[0003] The traditional vibration isolator uses rubber or metal spring as the elastic body. Although the vibration isolator with rubber as the elastic body has large damping, its bearing capacity is weak and the environmental conditions are harsh; the vibration isolator with various metal springs as the elastic body The biggest advantage of the isolator is that it can be designed and made into springs of various rigidities according to people's requirements, and it has a strong ability to bear loads. However, this kind of vibration isolator also generally has the weakness of large volume, large compression and almost no damping.

Due to these reasons, people are limited by many conditions when choosing traditional vibration isolators. In order to meet the requirements of certain indicators, some other performance requirements are often sacrificed, and sometimes the performance of machinery and equipment is also affected.
