Optimum Design for Seal Structure of a New-type Artillery Based on MOGA-Ⅱ and RSM
To solve the sealing and extracting problem of the semi-combustible cartridge case of a new-type artillery, the large-scale nonlinear FEA software ABAQUS was farther developed with Python language, and the parametrical finite element model for the seal structure was created. With the residual contact stress, the time for establishing a reliable seal as optimized objective, the length, the thickness and initial seal clearance as design variables, based on the multidisciplinary design optimization software mode FRONTIER, the seal structure was optimized via combining multi-objective genetic algorithm and the response surface method. The optimized results showed that 45.8% of the extracting force was reduced, and the time for establishing reliable seal was 5% ahead. Experimental results showed that not only the seal structure after optimization can obtain satisfactory results, but also the optimization strategy presented in the paper is a fast, efficient engineering optimum design methodology.
