A new algorithm directly based on 3D mesh model is presented to determine the reasonable stamping direction in CAE software. Compared with former similar optimization algorithms of the stamping direction, it can simplify the procedure and avoid the missing of some necessary details of complex parts, and it is automatic and intellective to determine the reasonable stamping direction. The feasibility of the algorithm has been proved by the creation of stamping directions of the automobile fender.

Geometric Simulation

The purpose of this paper is to geometrically simulate warp-knitted medical tubular bandages with a computer-aided simulator. A flat mesh model is established according to unfolded fabric considering the knitting characteristics of double-needle bed warp-knitted tubular fabrics. Moreover, a 3D (three-dimensional) mesh model corresponding to the actual product shape is created. To better describe the spatial geometry of stitches, eight-point models are introduced, and stitches are generated with the flat mesh model. Founded on matrix operations, the stitch position in the 3D mesh model is determined through coordinate mapping. Various stitch paths are rendered in computer programming languages C# and JavaScript to conduct simulations. Warp-knitted medical tubular bandages with a large number of shapes are effectively modeled.
