基于广义装配关系的复杂产品装配单元划分方法

通过分析复杂产品的装配几何关系,考虑夹具和工装在装配过程中的使用情况以及装配工艺性能,建立零部件之间的广义装配关系。在此基础上,构建以装配关系强度和装配并行度为目标的数学优化模型,采用免疫克隆算法进行聚类优化,完成复杂产品的装配单元划分。此方法不仅考虑零部件之间的广义装配关系,而且考虑单元划分的目的,使划分结果更加合理。最后,以某飞机机翼装配单元划分为例进行验证,结果表明该方法具有一定的适用性和有效性。

Assembly Unit Partition for Complex Product Based on Generalized Assembly Relationship

Generalized assembly relationships between parts are established,which include geometrical assembly relationships,fixtures and tools used in the assembly process and assembly process property.Based on assembly relationship intensity and assembly parallelism,a multi-objective mathematical optimization model is constructed.To realize assembly unit partition for complex product,immune clone algorithm is applied to clustering optimization.Both generalized assembly relationships between parts and the purpose of unit partition are considered so that partition result is more rational.Finally,the method is applied to the aircraft wing assembly unit partition.The result proves that the method is usable and effective.
