Abstract

A coupled-field analysis process for a RF cavity structure has been established. The commercial code ANSYS is used as the solver which successfully links analyses of different fields, including electromagnetics, heat transfer, and structure mechanics. The computation efficiency is thus dramatically improved. The calculated RF characteristics of a pill-box cavity match the theoretical predictions pretty well. The following thermal and structural computation based on the surface power loss are also performed. This coupled-field analysis process has been applied to a cavity in design. The computed results associated with RF are compared to the ones calculated by other codes
