Abstract: Aiming at the problems that assembly parts had different requirements on assembly resources in different assembly stages, the relationship between parts and assembly resources was analyzed by affordance theory, a matching design method of assembly resources based on assembly affordance model was proposed.Firstly, parts were analyzed by the assembly requirements.Then the assembly resources was matched by the assembly affordance 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 affordance model, which eliminates the assembly resources with negative interaction and choose the assembly resources to promote interaction, thus validating an effective method of select optimal assemblyresources.
Key words: assembly requirements; assembly affordance; assembly resource
