Abstract

Computer aided optimal design of helical compression springs is urgently required to promote the establishment of a national Egyptian standard specifications for such springs. The study covers the optimal assignment of spring variables for maximum modulus of resilience and achieving some functional constraints required for the satisfactory operation of the designed springs. Appropriate models and a fast optimization technique are used in solving the constrained optimization
problem in hand. Springs having more resilience and less weight were obtained in comparison with the standard springs. The results are presented for loads from 182.5 N to 2080 N and covers: resilience, stress, volume, spring mass saving and spring stiffness.
