ANALYSIS AND METAHEURISTIC OPTIMIZATION OF RAMSHORN HOOK WITH DIFFERENT CROSS-SECTIONS

Abstract

This paper presents the optimization problem of the cross-sectional area of Ramshorn hook at its most critical place. The geometric parameters of different profiles (triangular, parabolic and I cross-sections) are taken as optimization variables. The maximum stresses at the inner and outer fibers of a crane hook are taken according to Winkler-Bach theory (the constraint functions). The minimization of the cross-sectional area of Ramshorn hook is the main goal of this research (the objective function). As a method of optimization, one physics-inspired algorithm is taken to solve this optimization problem, called Improved Ray Optimization (IRO) Algorithm. The algorithm was applied in its source code, without modifications, using MATLAB software. The optimization results for all cross-sections are compared to show which achieves the best performance (savings in material).
