The Optimization of Combustion Chamber Components with Constrained Axisymmetric Sensitivity Analysis Algorithm

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.
