基于装配可供性模型的多阶段装配资源匹配研究

Multi-stage assembly resource matching based on assembly affordance model

针对零部件不同装配阶段对装配资源需求不同的问题,在分析零部件与装配资源的相互关系的基础上,提出了基于装配可供性模型的多阶段装配资源匹配设计方法。首先对零部件进行了装配需求分析,然后建立装配可供性模型和面向装配设计准则约束等分析工具进行了装配前、装配中、装配后3个阶段的装配资源自适应匹配,最后以齿轮和轴的装配为例验证了该方法选择最优装配资源的合理性与有效性。研究结果表明:运用装配可供性模型可以剔除对装配有消极交互作用的装配资源,选择对装配有促进交互作用的装配资源,从而验证了选择最优装配资源的有效性。

Aiming at the problems that assembly parts had different requirements on assembly resources in different assembly stages, the rela- tionship between parts and assembly resources was analyzed by affordanee theory, a matching design method of assembly resources based on assembly affordanee model was proposed. Firstly, parts were analyzed by the assembly requirements. Then the assembly resources was matched by the assembly affordanee model and design for assembly constraints analysis tools at the before assembly, assembly, after assembly of three stages. Finally, the rationality and effectiveness of selecting assembly resources was proved by the example of the assembly of gear and shaft. The results indicate that the assembly resources of satisfied assembly requirements were analysed by the use of assembly affordanee model, which eliminates the assembly resources with negative interaction and choose the assembly resources to promote interaction, thus vali- dating an effective method of select optimal assemblyresources.
