Research on the Key Technologies in Optimization of A Self-sealing Flange

摘要

This paper deals with a self-sealing flange system using O-ring as the potted component, and defines the design variables, restrictions and object function in the optimization. This study analyzes sealing performance of the flange system and quantifies it in optimization, and introduces the parameter of "maximal sealing gap" in optimizing computation instead of the concept of "sealing performance" which is too abstract to calculate, and then this paper analyzes the flange bolting and deduces the just bolt group of the flange system.
