Frequency Analysis of a rotating shaft

OBJECTIVE :

• To create 3D model of a rotating shaft.
• To perform frequency analysis on it and find out the critical frequencies.

SOFTWARE USED : Solidworks FEA

MODEL :

First, a sketch of shaft is made with the following dimensions.

It is then extruded and the model looks like :

FREQUENCY ANALYSIS :

Now, new simulation study is created.

Material Used : Alloy Steel with the following properties :

Default mesh is used.

Default setting of frequency analysis is used.

Bearing supports are given to the ends.

And finally, the simulation is run and the following results were obtained.

RESULTS :

Five results were obtained.

1.

2.

3.

4.

5.

Comparing the last four.

All the frequecies are tabled below :

CONCLUSION :

From the data, we can say that the component is safe to use except at the condition where the working frequency matches the resonant frequency we found.
