Frequency Analysis of a rotating shaft

AIM: To perform a frequency analysis on a Rotating shatf using solidworks to obtain resonance frequencies for different modes.

OBJECTIVES:

1) Make the model of the Rotating shaft having a disc on it by assuming dimensions.

2) Perform Frequency analysis on the model.

3) Obtain Different modes and list the resonant frequencies.

MODEL:

> The model drawings are as following:

FREQUENCY ANALYSIS:

> In this analysis the model is analysed for different mode shapes to obtain resonant frequencies.

> The input parameters used for the study are:

1) Material = Alloy Steel

2) Fixtures = Bearing supports on the stepped faces of shaft. (in order to rotate the shaft)

3) Mesh = Basic mesh

RESULTS:

> The results are obtained in the form of Amplitude of the resonant frequency:

AMPLITUDE-1

AMPLITUDE-2

AMPLITUDE-3

AMPLITUDE-4

AMPLITUDE-5
