Improving the Durability of the E.O.T. Crane Structure by Finite Element Analysis, and Optimize the Hook Material for Improving its Solidity

Abstract

Modern technological period can‘t be imagined without various material handling equipments. Cranes are amongst one of the material handling equipment which finds wide applications in different fields of engineering. Due to incredible all around economic development, the operation rate of cranes has astonishingly increased year by year, and many cranes are often used beyond their capacity in India. So Analysis of the main structure is very important and essential. The purpose of this paper is to analyze the stresses and strains condition in the power structure of overhead crane, presenting a fast and evaluated computer aided solving method for complex static indeterminate structures. The analysis of the stresses and strains state of the power structure of overhead crane bridge for increasing its toughness is made using the NX NASTRAN. The research performed allows the evaluation of the stresses state, pointing out the critical areas and measures which are imposed in order to increase the toughness of the power structure for the overhead crane. The results obtained allowed us to make up a study about the dimension optimization of the power structure in order to design the crane hook. Thus, the material use could be reduced without more than the limits of the most suitable conflict.
