Cost Optimization of Elastic Energy Absorbers in Car Bumper for Impact Application using Kuhn-Tucker, SLP, CSD and PLBA algorithms

Elastic energy absorbers which consist of ring-liked plate and springs can be a good choice for increasing the impact duration during an accident. In the current project, an energy absorber system is optimized using four optimizing methods Kuhn-Tucker, Sequential Linear Programming (SLP), Concurrent Subspace Design (CSD), and Pshenichny-Lim-Belegundu-Arora (PLBA). Time solution, convergency, Programming length and accuracy of the results were considered in order to find the best solution algorithm. Results showed the superiority of PLBA over the other algorithms.
