The Analysis and Inspection Technology of Product Assembly Properties for Virtual Assembly Based on Assembly Force

In the paper the need of virtual assembly property analysis was discussed，the indexes system of the product assembly properties was constructed based on assembly force. The mechanical model of strength and reliability analysis was established for hole and axle interference fit joint in virtual assembly. The mechanical model of strength and reliability analysis was established for key joint. The analysis and inspection technology of the product assembly properties for virtual assembly was put forward based on assembly force. The system of product assembly properties analysis was developed, and the system was tested by gear reducer.
