Implementation and application of automatic parametric design of 2d nonlinear fea

摘要

This paper presetns implementation and application of automatic parametric design of 2D nonlinear FEA. Parametric design inveolves iterating on a FEA solver and preprocessor. Global quantities and linked database files provide the basis for analyzing the analyses. Parametric analysis of two disks contacting shows an expected relationship between interference, land height, and stress. Lastly, the assembly of press fit tubes shows the relationship between interference, contact area, and normal force.
