Abstract
To improve the situation of stress concentration in the combustion chamber component, optimized the design of combustion chamber shell structures is required. In this paper, a new boundary element integrated optimization method is used. There are a symmetry axis structure and effective constrained optimization model for sensitivity analysis. The technology and the general shape optimization algorithm are combined. The components' shape of the combustion chamber's shell under a plane stress is optimized, and finally, the satisfactory results are obtained and the maximum tangential bore stress is reduced.
