Design and Development of Compression and Torsion Springs Using CAD/CAE

What is it about?

Abstract: In this paper we displayed the problematic of spring design, with usage of CAD/CAE (Computer Aided Design/Computer Aided Engineering) methods. Spring 3D (Three-dimensional) parametric modeling is performed in CATIA (Computer Aided Three-dimensional Interactive Application) software for purposes of achieving fast manipulation of spring geometry, so various spring variants can be made. Using the same software, FEM (Finite Element Method) analysis is used to determine maximum stresses and deflections. Utility of developed parametrized spring system is best reflected for cases of new spring design, where new geometric and FEM models are created with simple parameter application and update feature. This research resulted in spring prototyping with utilization of 3D printing techniques and spring manufacturing.
