Failure Analysis of Excavator Bushes and Induction Hardening With Different Case Depth Using FEA Approach
Kundan S. Ghinmine,  Prof. U. S. Pawar
Wear of a pins and bushes is normal, but the rate of wear can be unnecessarily increased by factors such as inadequate and improper lubrication, overloading, misalignment of parts or failure of adjacent parts. Uneven loading on pins and bearings may also cause the failure. In our project, we are going to apply induction hardening process on pins and bushes and its comparison will be done with existing pins and bushes .Different hardening thickness or case depth will be applied and analysis will be done to interpret the results. Existing bush will be replaced with steel, brass and bronze alloy. The main objective in this project is to determine the appropriate induction hardening case depth to be used in fabricating pins and bushes. Three-dimension models of bushes used in excavator were created using CatiaV5 software, meshing will be done using Hypermesh and Ansys will be used to analyze the stress status on the pins and bushes. The maximum deformation and maximum stress point found by the stress analysis.
