Integrated vibration absorption and isolation pipeline bracket

Abstract

The invention discloses an integrated vibration absorption and isolation pipeline bracket, and belongs to the technical field of vibration noise control. The bracket comprises an upper clamping ring, a rubber pad, a lower clamping ring, a vibration absorption component, mounting plates and vibration isolation components, wherein the vibration absorption component consists of a mass component, two frequency modulation components and two elastic components; the two frequency modulation components and the two elastic components are symmetrically and fixedly mounted on upper and lower mounting planes of the mass component respectively; each frequency modulation component consists of a frequency modulation bolt and a nonlinear rigid component; the two vibration absorption components are arranged in a cavity of the lower clamping ring, and are fixedly connected with the vibration isolation components through the elastic components and the mounting plates; the lower clamping ring is fixedly connected with the vibration isolation components through the mounting plates; a pipeline is mounted in middle of the rubber pad; the upper and lower clamping rings are fixedly connected to lock the rubber pad. According to the bracket, the line spectrum and wideband vibration of a pipeline of a warship can be effectively suppressed, a small mounting space is required, and the bracket is convenient to assemble, disassemble and maintain.

Description

technical field [0001] The invention relates to a pipeline support, in particular to a vibration absorption and isolation integrated pipeline support, which belongs to the technical field of vibration and noise control. Background technique [0002] The equipment-pipeline-base on the ship is one of the important channels for vibration transmission. The vibration transmitted by the pipeline includes not only the prominent characteristic line spectrum caused by the operation of the equipment, but also the broadband vibration caused by factors such as flow excitation. Reducing the vibration transmitted by these pipelines is of great significance for improving the stealth performance of ships. [0003] For the broadband vibration of the pipeline, it can be effectively controlled by installing a vibration isolation bracket; for the low-frequency line spectrum vibration of the pipeline, it can be significantly reduced by installing a vibration absorber. Therefore, there is an ob...

Problems solved by technology

At present, domestic and foreign pipeline supports only have the function of vibration isolation or vibration absorption, which cannot meet the requirements of vibration absorption and isolation at the same time.
