Static and Harmonic Analysis of Winch Shaft using FEM

Abstract

It is not easy to lift the heavy loads with bare ropes or other components. Winches are very useful for various mechanical applications. In this present work, winch shaft is designed and analysed using Finite Element Method (FEM). Catia and Nastran programs are used for the modelling and analysis. Static and Harmonic analysis are carried out on the winch shaft. In static analysis the maximum displacement induced is .009817 mm, hence based on Rigidity, and stresses in Z-direction are observed to be 0.122E -0.7 mm and 158.731 N/mm2 respectively. The maximum stress and fundamental frequencies found are 119.009 MPa and 143.98 Hz. The deflection value from theoretical calculations is 0.013 mm. The mathematical relations are used for the validation of the analysis and found good agreement.
