On the background of selecting an optimal combination of elastic pads " height between the two adjacent cylinders , which carry out the design requirement of combinative cylinders assembled structure , in this dissertation , the optimal design model is established ground on geometrical and mechanical model of the combinative cylinders assembled structure . the algorithm that integrates multi - objective ' s decision - making method with minimal distance between two points in euclid ' s space into the modified genetic algorithm to solute the optimal model is presented 本文以选取层间弹性垫层厚度实现组合圆筒裱糊装配结构的设计要求为研究背景,依据组合圆筒裱糊装配结构的几何模型与力学模型,建立组合圆筒裱糊装配结构的优化模型,提出改进遗传算法与欧几里德空间最短距离准则的多目标决策方法相结合的优化算法。
