Application of Orthogonal Experimental Method in the Sealing Design of a Bolted Flange Connections

Abstract:

The paper aims to provide a theoretical method of multi-parameter optimization collocation for sealing structure design. Based on the tightness analysis method, the paper analyzed the effects of several major influence factors on the maximal gasket contact stress. Some sensitive parameters were chosen according to the tightness analysis results. Orthogonal experiment method was applied in the current work to find the optimum combination of parameters which will contribute to a better sealing performance of the connections. The theoretical way proposed in this paper can effectively shorten the design period and is helpful to improve the quality of the design and reduce the design cost.
