Optimization of mechanical design problems using advanced optimization technique

Abstract

In design of mechanical elements, designers usually consider certain objectives that are related with cost, time, quality and reliability of product depending on the requirements. In this paper, parametric optimization of spring design problem and pressure vessel design problem has been carried out using Amended Differential Evolution Algorithm (ADEA). ADEA is modified DE that can handle constraint and complex problems effectively. In spring design problem, parameters are optimized to reduce volume of compression and in pressure vessel design problem, parameters are optimized to reduce total cost. The results obtained using ADEA are compared with the results reported by other researchers. The comparison of results shows that ADEA provides better results for both spring and pressure vessel design problems.
