| Abstract: | The dynamic stress in helical spring has been analyzed with a spatial mechanical model for bent lever and an analytic solution for the partial differential equation has been found. A dynamic optimal design for the spring is then carried out. The objective function for optimization is based on the minimization of the maximum dynamic shearing stress in the spring. The mixed discrete variables optimization program CVM02 is used, and the design results are found to be satisfactory. |
