Investigation of the Effect of Parameters on the Tightness

Abstract

Abstract The Center Composite Design (CCD) is built as a surrogate computationally expensive numerical simulations to improve the efficiency of the optimization design of metallic gas-ket. The optimization of important parameters such as wavy height, top flange thickness and gasket thickness is the goal of optimization by the CCD. Higher gasket thickness, wavy height and top flange thickness are beneficial to the improvement of sealing reliability. By comparing the optimization results with the finite element analysis results and test results, the results show that the coincidence is high and the design efficiency is greatly improved.
