ANALYSIS OF A FLYWHEEL

USING ANSYS 14.0

Author: Tushar Dange

Updated by: Tushar Dange

Programs Used: ANSYS 14.0, CATIA V5R20

Introduction:

In this tutorial, finite element flywheel will be constructed and analyzed. The analysis is based on the stresses and deformation with respect to the load get applied such as 500 lbs. The flywheel is fixed at center and spinning in the clockwise sense.

Also, the material I used is a cast iron with E=100 GPa, G=30 GPa, rho=7000kg/m^3, poisson's ratio= 0.29

The cross section of a flywheel is as shown below:

The Programs used:

CATIA V5R20, ANSYS 14.0

Introduction to CATIA V5R20:

It's a powerful 3D software which allows the user build the three dimensional model. In this software, number of designs can be done like wire diagram, surfacing, solid modeling, and so on. The saving of data is useful in doing the design work.

Introduction to ANSYS 14.0:

It's also the one of the powerful finite element analysis software package which allows the user to build the geometry, solid modeling, apply the loads, and so on. The saving of data is useful otherwise chances of losing the work done.

Starting with CATIA V5R20:

As per the 2D diagram shown above, I have started with basic originating the points. The center part was the first one which is hub.

By creating a diagram, I have made the extrusion as per the requirement and then protruded. The next step was making the circular protections to the hub such as rim with the shown dimensions with the applicable protrusion tool for making it solid.

By making an angular lines (45 degrees) by keeping hub as a center, I have created the arms as shown above with the respective dimensions.

At the end, by using an extrusion tool, the flywheel get created as follows:

Geometry:

Starting with ANSYS 14.0:

The main work has started. By importing the flywheel from CATIA, the work has done in half way. The only remaining part was the applying material properties, load, meshing, and the analysis part in workbench which has done as follows in figures such as:
