摘  要:文章采用有限元计算法和蚁群算法,对罐装水泥运输船船体结构设计方案进行结构计算分析,结果显示:采用去除高应力区域结构以阻断载荷传递的方法比增强船体梁甲板结构的方法更为合理,对于改善结构局部高应力水平具有比较优势;通过蚁群算法对目标船货舱区域中剖面结构进行优化设计,以每个板格的板与加强筋的厚度、纵骨间距为设计变量,以单位长度结构模型重量最轻为目标函数,以中国船级社《钢质内河船舶建造规范(2016)》中关于直接计算的边界条件要求为优化算法的边界条件,选取合适的优化参数,使得优化后的结构重量下降10.44%。文中采用的结构调整方式及优化方法可为同类船型的设计提供参考。This article uses the finite element method and the ant colony algorithm to conduct the structure calculation analysis on the hull structure design of canned cement carrier,the results show that the method of removing the high stress area structure to block the load transfer is more reasonable than the method of reinforcing the hull beam deck structure,and it has a comparative advantage on improving the local high-stress level of the structure;through the ant colony algorithm,it conducts the optimization design for the midship section structure of cargo area in target ship,then,with the thickness of the plate and the stiffener at each plate grid and the longitudinal bone spacing as the design variables,with the lightest weight of unit length structure model as the object function,and with the boundary condition requirement about the direct calculation in“Steel Inland Ship Construction Code(2016)”of China Classification Society as the boundary conditions of optimization algorithm,it selects the suitable optimization parameters,which makes the structure weight drop by 10.44%after the optimization.The structure adjustment method and optimization method adopted in this article can provide the reference for the design of similar ships.
