Analysis & Induction Hardening On Excavator Pins

Pins require very little service and total failure seldom occurs. Wear, pitting, and scoring are the usual troubles encountered with pins. In this paper, going to apply induction hardening process on pins and its comparison will be done with existing pins. Different hardening thickness or case depth will be applied and analysis will be done to interpret the results. Case depth of 1mm, 2mm or 2.5mm will be taken in induction hardening process. Caterpillar 320dl excavator model is taken for study. Material used for the pins is EN8 grade of steel. And different material used for the pin for analysis purpose will be bronze alloy, Titanium. The main objective in this project is to determine the appropriate induction hardening case depth to be used in manufacturing pins.Threedimension models of pins used in excavator will be created using CatiaV5 software, meshing will be done using Hypermesh and Ansys will be used to analyze the stress status on the pins. The maximum deformation, maximum stress point and dangerous areas are found by the stress analysis.
