中文摘要：

模块化设计能够缩短产品研发周期，提高产品的性能，可拆卸设计将绿色设计思想拓展到产品的全生命周期。综合模块化设计方法和可拆卸设计的思想，提出了可拆卸设计的模块化准则，以可拆卸度、内部聚合度、外部耦合度为优化目标进行模块划分。针对免疫克隆算法在模块划分问题上，最优Pareto解集分布不均匀的问题，改进了一种免疫克隆算法（immuneclonalalgorithm，ICA），该算法通过删除非支配抗体中较为拥挤的抗体，得到了分布均匀的Pareto解集。利用该算法进行模块划分，得到了模块划分的优化结果，该方法以模块划分为主要目标，同时兼顾了模块零部件之间可拆卸性的复杂程度，最后以飞机起落架为例说明了该方法的可行性和适用性。

英文摘要：

Modularization design has advantages such as shortening the period of product development,improvingproduct performance.Removable design expands green design idea into the full life cycle of products.This paper integratesmodular design method and the removable design idea,and the removable design rules of modularity is proposed.Takingremovable degrees,internal polymerization degree,external coupling degree as optimization objective,the module partitionis done.According to the problem that ICA can’t get uniform Pareto optimal set when solving module partition problem,an improved ICA is proposed,which deletes non dominated antibody from where antibody is crowded.This method get abetter Pareto optimal set.Then taking module division of the aircraft landing gear by the improved ICA as an example,theresult shows this method is feasible and applicability.
