Static Structural Analysis of a Flywheel-Shaft Assembly Using Shrink Fitting for Static & Dynamic Conditions- A Review Study

Manufacturing & production industry is driven by heavy machinery being employed on large scale in order to meet the requirements of today’s world. It has to carry out the production and manufacturing work day in and day out to match the ever-increasing demands from different sectors of the society. Here the machinery components need to work more than their rated capacity which sometimes causes severe failure and damages in components. Because of the large-scale competition which is present today in this industry, machinery components are not even allowed to fail. Rotating components play an important role in any machinery & they are very sensitive to handle. One key feature of the rotating components is how we connect two components which are in rotation with each other. Normally to connect two components we use fitting methods which are of mechanical type fitting & shrink fitting. In this dissertation we are analyzing the effects of shrink fitting between a shaft and flywheel when flywheel is mounted over the shaft using shrink fitting. The process parameters to be used will be hoop stress, radial interference, torque capacity and strain. The calculations will be done for standstill condition, rated RPM & runaway RPMs of the machinery components. The study would be completed in two steps. In first step, data will be calculated analytically using previous literature, empirical relations or mathematical calculations using formulae provided by reference books of respective subjects. Then in second step to validate the data a finite element simulation of the component assembly will be performed on ANSYS-19.0 workbench with 3D model of the assembly being created in PTC Creo 6.0.0.0/CATIA V5 R20. The results of both kinds of analysis will be compared with each other & hence a comparative analysis will also be performed.
