Abstract
The invention discloses a pipeline particle-impact damper and a design method thereof. The pipeline particle-impact damper comprises a pair of semicircular clamping parts connected through a first bolt and a first nut; each semicircular clamping part of the pair of semicircular clamping parts is partitioned into three cavities through two steel plates; the cavities are loaded with particles; the filling rate of the particles influences the vibration reduction effect on a pipeline; the two sides of the cavities of the pair of semicircular clamping parts are sealed through semicircular thin plates correspondingly, wherein the particles vibrate, collide and rub in the cavities of the pair of semicircular clamping parts so that vibration is reduced in a system energy consuming mode; semicircular grooves are formed in the centers of the semicircular clamping parts; and the two semicircular grooves form an arc for clamping the pipeline after the pair of semicircular clamping parts are matched. The pipeline particle-impact damper and the design method thereof are based on the added damping basic thought, the structure is simple, mounting is convenient, and the pipeline particle-impact damper can meet the requirements of vibration reduction operations at different pipeline system working frequencies under the condition that the pipeline particle-impact damper does not need to be adjusted.
Description
technical field [0001] The invention relates to a steel structure particle collision damper for reducing pipeline vibration and a design method thereof, belonging to the technical field of vibration control. Background technique [0002] The pipeline vibration particle collision damper is a passive shock absorber based on the additional damping method, which can effectively solve the problems of not being able to apply the clamp and change the pipe shape, and for the complex working conditions of the pipeline system, it can Under the realization of the installation and achieve the purpose of vibration reduction. Due to the energy consumption mechanism of collision friction, even for different pipeline systems and different vibration frequencies, the purpose of reducing pipeline vibration can be achieved. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the purpose of the present invention is to provide a pipeline particle col...
