Abstract

Crane hooks are important components from safety point of view since they are subjected to large amount of stresses. Hence to study the stress pattern in crane hooks; analytical, numerical and experimental methods are used. For analysis purpose virtual model of crane hook is prepared by picking data from design data book. Curved beam formula is used for determination of stresses in crane hook analytically. For numerical analysis CAD model of crane hook is prepared using Pro-E and this model is imported in ANSYS where stress analysis is done by FEM. Finite Element Analyses have been performed on various models of crane hooks having trapezoidal, modified trapezoidal, circular and rectangular cross sections. Also for rectangular hook stress analysis is done by using method of photoelasticity. From the output of these analyses it is observed that results obtained are in close agreement with each other and maximum stress concentration occurs at inner most surfaces.
