IDENTIFICATION OF SHRINKAGE DUE TO MODULUS OF FLYWHEEL CASTING BY USING PROCAST SOFTWARE

Abstract

A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheel has a significant moment of inertia, and thus resist changes in rotational speed .The amount of energy stored in a flywheel is proportional to the square of its rotational speed. Rejection rate is one of the major issues in Indian foundry. Foundries try to reduce rejection by experimenting with process parameters or modifying method and tooling design which reduces the quality of castings and increase cost of production.Shrinkage, blowhole, porosity, etc. are the main casting defects which is responsible to increase casting rejection rate. In present theories, flywheel model is simulate& update the results. Shrinkage is open when we take a cross section of flywheel casting.Modulus is the main parameter which is responsible to form cavity in the material. Modulus is relates with temperature cooling rate, solidification time, etc are the parameters to open shrinkage defect. Flywheel is the casting model & we have open the casting defects in flywheel casting.
