A high-load fully sealed disc structure vibration isolation device

Abstract

A high-load full-sealed disc structure vibration isolation device mainly includes a cover plate, a disc structure vibration isolator and a bottom basin. The vibrator is a center-symmetrical structure, its central part protrudes upwards to form an elastic deformation part, and the outer edge of the elastic deformation part extends outwards to form a support part. The center of the elastic deformation part is a support platform, and the upper surface of the support platform and the cover The lower surface of the plate contacts and cooperates with each other. The lower surface of the support platform does not contact the upper surface of the bottom basin. A plurality of holes are opened on the segment, and the thickness of the cone segment gradually decreases from the support platform to the support portion. The invention realizes the vibration isolation effect in the form of a pure structure, is placed on the support part of the vibration-isolated body, and the vertical stiffness is appropriately reduced, and the vertical fundamental frequency is far away from the main frequency of the vibration of the upper structure, thereby realizing the vertical vibration isolation function.

Description

technical field [0001] The invention relates to the technical field of vibration isolation used in equipment, bridges or buildings, and specifically relates to a vibration isolation device with a high-load full-sealed disc structure. Background technique [0002] The vibration isolation device is an elastic element connecting the superstructure such as equipment, bridge or building and the foundation, to reduce and eliminate the vibration transmitted from the superstructure to the foundation and the vibration transmitted from the foundation to the superstructure. Currently commonly used vibration isolation devices include steel spring vibration isolators, metal rubber vibration isolators, rubber vibration isolators, air cushion vibration isolators, and vibration isolation pads. The above-mentioned vibration isolation devices have their own applicable working conditions, but all have the disadvantage of small bearing capacity. When the self-weight of the upper structure is s...

AI Technical Summary

Problems solved by technology

The above-mentioned vibration isolation devices have their own applicable working conditions, but they all have the disadvantage of small bearing capacity

When the self-weight of the upper structure is small, it can meet the bearing capacity requirements, but when the weight of the upper structure of the vibration isolation device reaches 100 tons or more, unless the number of vibration isolators is greatly increased, it is difficult to meet the bearing capacity requirements

However, if there are too many vibration isolators, the basic structure will inevitably become larger, which will not only increase the construction cost, but also increase the difficulty of designing the entire basic structure.
