摘　　要：结合CCS规范和薄壁杆件理论,建立了考虑弯扭强度和频率约束的集装箱船中剖面优化设计的模型,考虑到中剖面优化设计中的设计变量为连续和离散的混合变量,利用isight中集成的自适应模拟退火算法,建立了巴拿马型集装箱船中剖面优化设计系统,并对3100TEU集装箱船中剖面进行了优化设计,取得了合理的结果.The model is set up in view of the optimum design of midship section of container ships with crankle strength and frequency constraints according to CCS rules and thin-walled beam theory. Considering that design variables are continuous and discrete ones, the optimum design system with adaptive simulated annealing which can solve mixed variables optimum problems in ISIGHT environment is set up. The system is applied in the optimum design of the midship section of 3100 TEU container ship in this paper, and the ideal result was obtained.
