ENGAGEMENT PART ANALYSIS MODEL GENERATING METHOD, ENGAGEMENT PART ANALYSIS MODEL GENERATING APPARATUS, AND PROGRAM, AND ANALYSIS MODEL GENERATING METHOD

摘要

To automatically generate a mesh suppressing interference without preparing, in advance, a mesh corresponding to an engagement part of a model.SOLUTION: An engagement part analysis model generating method according to the present invention has an engagement part extracting step of extracting an engagement part for engaging a shaft formed of a convex curved surface in an aperture formed of a concave curved surface in a positional relationship between the concave curved surface and the convex curved surface included in a three-dimensional model, a mesh division number calculating step for calculating a mesh division number so that based on geometrical information and positional information of the engagement part, a mesh obtained by modeling the convex curved surface forming the shaft should be penetrated through a mesh obtained by modeling the concave curved surface forming an aperture by an allowable insertion amount or less, and a mesh generating step for generating a mesh at the engagement by allocating polyhedron mesh to a region divided based on the calculated mesh division number for each of the concave curved surface forming the aperture and the convex curved surface forming the shaft.SELECTED DRAWING: Figure 2
