PRIMARY RESEARCH ON FSI VIBRATION OF BELLOWS

Luo Hong-han

Abstract

With the background of the cooling system of monochromators at SSRF,considering the special structure of bellows and based on the vibration theory of general flow-conducting pipe system,the flow-induced vibration of bellows was studied.The numerical method was chosen to construct the model of the bellow-fluid system and the feasibility of the software of ANSYS for solving FSI (Fluid-structue interaction) problems was validated.The study of the mechanism of FSI vibration of bellows and the analysis of its features are the key problems in the research.The counter-vibration measures were given according to the computational results.
