Weather-resistant durable all-metal multipoint frequency selection vibration suppression structure

Abstract

The invention discloses a weather-resistant durable all-metal multipoint frequency selection vibration suppression structure which comprises a bracket plate and a plurality of vibration suppression assemblies. Square holes are formed in the bracket plate, the vibration suppression assemblies are arranged on the bracket plate and comprise mass blocks, elastic modules and cushion blocks, one end ofeach elastic module is positioned in the corresponding square hole, each mass block is adhered at the end of the corresponding elastic module, the other end of each elastic module is positioned on theupper surface of the bracket plate, the cushion blocks are arranged on the lower surface of the bracket plate and are positioned below the elastic modules, the elastic modules comprise first materiallayers, second material layers and third material layers, and the first material layers, the second material layers and the third material layers are arranged in a step-shaped manner from top to bottom. The weather-resistant durable all-metal multipoint frequency selection vibration suppression structure has the advantages that the weather-resistant durable all-metal multipoint frequency selection vibration suppression structure is a plane structure and is thin, the size of the weather-resistant durable all-metal multipoint frequency selection vibration suppression structure can be flexibly designed, and accordingly the integral weather-resistant durable all-metal multipoint frequency selection vibration suppression structure can be easily arranged in different types of narrow mechanicalequipment, is simple and is convenient to assemble; materials required by the weather-resistant durable all-metal multipoint frequency selection vibration suppression structure are conventional materials, accordingly, batch processing and production can be facilitated, and the weather-resistant durable all-metal multipoint frequency selection vibration suppression structure is worthy of being popularized and utilized in the industry.

Description

technical field [0001] The invention belongs to the technical field of vibration control and composite materials, and in particular relates to a weather-resistant and durable all-metal multi-point frequency-selective vibration suppression structure. Background technique [0002] In the field of mechanical engineering, vibration can be said to be ubiquitous, and vibration is often harmful to most engineering structures and mechanical equipment. Mechanical vibration will not only cause fatigue damage to the structure of some parts, reduce the measurement accuracy of precision measuring instruments, and even have a greater impact on the performance and life of the equipment and even lead to damage to the structure of the equipment. For manned mechanical equipment, low-frequency vibration will seriously endanger the physiological health of the occupants, cause the imbalance of human organs, cause dizziness, heavy head, fatigue, loss of concentration, etc., and sometimes may caus...
