Frequency Analysis of a rotating shaft

AIM: To perform frequency analysis on a rotating shaft

PROCEDURE:

• Create the model and save the part
• Setup a new frequency analysis simulation
• Assign material to the body as alloy steel
• Right click on the frequency analysis tab and make sure 5 modes of frequencies are entered

• Generate a mesh
• Run the simulation
• Obtain results

MODEL AND MESH:

RESULTS AND DISCUSSION:

The solver has computed all 5 modes of vibration and the results are as follows

From the above table, we infer that the 4^th and 5^th modes of vibration display a very high vibration (1245.5 Hz). So it is necessary to make sure that no external source that is in contact with the must vibrate at 1245.5Hz or else, the system would reach resonant condition and begin to vibrate.
