| Abstract: | Mathematical model of multi-layer composite artillery barrel with ceramic liner was built by using axisymmetric elastic theory, and stress computer program of the composite barrel was developed. Multiobjective optimization model was established, and the program was incorporated in multidisciplinary optimization software iSIGHT. Optimization was carried out by multiobjective genetic algorithm, and Pareto optimization solution was obtained. Finite element simulation and verification of selected optimal solution were carried out by universal finite element code MSC.MARC. The results prove that the method is effective to solve the similar problems as multi-parameter optimization of complex structures. |
