This document presents a project on the design and stress analysis of a crane hook. A group of 4 students will conduct finite element analysis and analytical analysis to determine the optimum material for withstanding maximum load with minimum stress. The analysis will be conducted in two phases: 1) FEA of an approximate model verified with Taguchi method, and 2) analytical beam analysis. The project aims to increase the life and strength of crane hooks by establishing relationships between theoretical, experimental and FEA stress results. Various materials and loads will be considered in Taguchi experiments. Facilities for completion include ANSYS and other software.

2. Introduction
Need of the project
• Computer aided design and analysis of hook.
Scope of the project
• Find out the optimum material for designing a crane hook which would lift
maximum amount of load with the minimum effect of stresses.
Methodology
The analysis is carried out in two phase:
1. FEA of an approximate model and its verification by Taguchi Method
2. Analytical analysis as the hook is a curved beam
Expected outcome
1. By this proposed work eventually the life and the strength of the crane
hook will be increased.
2. By this proposed dissertation work, a clear idea of variation in stresses
between theoretical, experimental and FEA results can be established.

3. Review of Literature
• E. Narvydas et. al[1] , investigated circumferential stress concentration factors
• Rashmi Uddanwadiker[2], studied stress analysis of crane hook using finite element
method and validated results using Photo elasticity.
• Santosh Sahu and et. al[3]; they designed an experiment in which the varying the length
of two parallel sides of the Trapezoidal Hook
• Govind Narayan Sahu and Narendra Yadav[5]; investigated that, the Stress induced and
displacement in “Modified Curved Hook”
• Mr. A. Gopichand, et. al[6]; investigated on the optimization of design parameters using
Taguchi method
• Ajeet Bergaley and Anshuman Purohit[7]; they investigated that Maximum Stress is
generated at the point on the hook

4. Aims & Objectives
• Calculate the stresses produced in Crane Hook of
different materials at different cross-sections.
• Von-misses stresses at different cross-sections FEA
analysis of Crane Hook.
• Analytical and FEA results to find best suitable
material for high load condition
• Increase the life and the strength of the crane hook.
• Stresses between theoretical, experimental and FEA
results can be established.

5. Basic Theory
Finite Element Method :
The finite element method (FEM) is a numerical technique for
finding approximate solutions of partial differential equations as
well as of integral equations.
Finite element Modeling :
Finite element analyses were performed using ANSYS to simulate
the deflection and stress of Crane hook. ANSYS includes general-
purpose solid elements as well as elements that are valid for solid.
Taguchi Method :
A method based on ‘Orthogonal Array’ experiments which gives
much reduced variance for the experiment with ‘Optimum settings’
of control parameters.
