組み立て時の製品変形を考慮した公差解析手法

抄録

In recent years, 3D-clearance analysis is used in the manufacturing industry. By using the clearance analysis, we can check the interference between the components. On the other hand, many products have been reduced in thickness for lightweight and cost reduction, so we have to check deformation of a product at the time of assembly of components. But it was too difficult for us to check deformation at the time of assembling because clearance analysis cannot express the deformation. In this paper, we show the way to combine clearance analysis with FEM analysis by quality engineering.
