Abstract:
Light weight and high stiffness composite material barrel can be obtained by a structure opt imal design. According to the design requirements, the structure opt imizat ion model of a composite material barrel is established. The stiffness of barrel is defined as design objective. The thicknesses and winding angles of the composite material layers are defined as design variables and the structureweight and strength of barrel as constraints. Integrated with finite element method and complex method, the optimization solution frame is established and the code is developed. An optimal example indicates that the fundamental frequency of the composite material barrel increased by 12. 14% with the requirement of strength and weight of barrel.
