Cross section shape optimization design of fabric rubber seal

In this paper, the cross section shape of fabric rubber seal is designed and optimized. First, the cross section shape optimization design method is introduced based on the structural features of fabric rubber seal. Then, according to the key performance of fabric rubber seal, the optimization constraints, optimization objective and corresponding calculation methods are determined. Finally, the optimal cross section shapes of fabric rubber seal are obtained under different gas pressure differences, temperatures and multi-objective optimization design. The results indicate that the shape optimization method has an important guiding for the design and manufacture of the fabric rubber seal.
