Abstract

The invention provides a metal rubber-disc spring all-metal three-way composite support for piping vibration isolation and impact resistance. The metal rubber-disc spring all-metal three-way composite support comprises metal rubber mats and disc springs, a center net, a locking nut, a pressure cover, a guide holder, a mounting base and a base plate, wherein the metal rubber mats and the disc springs are used for bearing vertical vibration and impact load, the center net is used for bearing horizontal vibration and impact load, the locking nut, the pressure cover, the guide holder, the mounting base and the base plate are used for supporting and fixing an elastic component. By the aid of large bearing capacity and flexible rigidity characteristic, Coulomb damping among the disc springs, and the Coulomb damping between hard rigidity characteristic of the metal rubber mats and the disc springs, the flexible and hard rigidity complex characteristics and larger damping on the vertical bearing direction can be realized. The metal rubber-disc spring all-metal three-way composite support is compact in structure, light in weight, high in high-temperature environment adaptability, good in damping capacity, and lower in vibration isolation frequency, and vertical rigidity has higher static rigidity and lower dynamic rigidity; besides, considerations are also given to shock isolation and a limiting function, so that three-way impact acceleration responses and impact displacement responses can be kept within a reasonable range.

Description

technical field

[0001] The invention relates to the technical field of design of vibration isolation and impact resistance devices, in particular to a metal rubber-disc spring all-metal three-way composite support for vibration isolation and impact resistance of pipelines.

[0002] Background technique

[0003] The impact protection performance of the gas turbine intake and exhaust piping system in the impact environment is a relatively weak link, which directly affects the operation function of the entire ship power system and is related to the vitality of the entire ship. The results of the actual ship explosion test show that the impact resistance of the pipeline system is an important issue that cannot be ignored, and its impact resistance is directly related to the vitality and combat effectiveness of the ship.

[0004] In naval vessels, pipe supports are often used in conjunction with pipe hangers as elastic support elements for pipe systems. Its primary function is ...
