Crash performance optimization of vehicle elements using arithmetic optimization algorithm

Abstract

In this study, the newly developed arithmetic optimization algorithm is used for the first time in the literature for the optimum design of automobile components exposed to crash. In conjunction with the enhancement of crash and NVH characteristics in the optimization study, the design objective is to minimize vehicle weight. For vehicle performance analysis, a comprehensive automobile structure, faithful to the original, was used. Both multiple crash analysis and vibration analysis of finite element models were performed to examine full, offset and side impact crash scenarios with natural frequencies. The evaluated structural responses are estimated based on the radial basis functions technique. An arithmetic optimization algorithm is used to optimize the vehicle mass under various nonlinear crash and vibration limits. The results revealed the effectiveness of the arithmetic optimization algorithm in the optimum design of vehicle components.
