Geometric Design Model and Object Scanning Mode Based Virtual Assembly and Repair Analysis

The machining precision of composite material parts is usually not very high, thus for virtual assembly of composite material parts, it is difficult to simulate the actual assembly situation only by using geometric design models. This paper proposes a virtual assembly and repair analysis method based on both geometric design model and object scanning model. By matching the scanned cloud point model to the design model, the virtual assembly process is constructed, and the repair analysis is implemented according to the results of virtual assembly. The proposed method is investigated by truss structure, and the results show the effectiveness of the proposed method.
