Multi-Objective Optimization Design of CFRP Winding Mortar Barrel with Metal Liner Based on MOPSO

摘要

A model of composite mortar barrel made of carbon fibre reinforced plastic (CFRP) jacket and steel liner was developed based on the finite method. The multi-objective particle swarm optimization (MOPSO) was employed for the multi-objective design of composite mortar barrel during design processing. The winding angle of carbon fibre and the thickness of composite layers are defined as optimization variables. The fundamental frequency and structure weight of barrel are defined as optimization objectives. The Pareto solution set of composite mortar barrel is obtained by MOPSO. The corresponding design solution of composite mortar barrel is improved in stiffness and weight.
