Design and Dynamic Analysis of Crane Hook with Niobium Micro Alloying Steel

Abstract

The crane hook mostly subjected to failure due to accumulation of large amount of stresses which can eventually lead to its failure. Failure of a crane hook mainly depends on three major factors i.e. dimension, material, overload. The design of crane hook has been carried out. To minimize the failure of crane hook, the stress occurred in it must be studied Generally, the design of the hook is done for the different materials like SAE-AISI 1040, ASMT GRADE 60, Forged steel, wrought iron, Aluminium alloy, High strength low alloy steel, and Crome steel but I want to use the material of crane hook as a Niobium Micro alloying Steel. And analyse the all parameters of other materials with Niobium Micro alloying Steel. Pro-E Wildfire 5.0 software is used for modelling the crane hook and ANSYS software used to find out the stresses induced in it. This result helps us for determining of stress in existing model. By predicting the stress concentration area, the hook working life increase and reduce the failure stress
