Abstract
A finite element analysis (FEA) based coil spring design method that utilizes a reverse engineering based concept. The method involves first designing a desired jounce profile, which is typically an output in the conventional FEA based design, and then reversely determining the corresponding free profile necessary for manufacturing a spring having desired performance specifications.
