Frequency Analysis of a rotating shaft using Solidworks

AIM: To conduct frequency analysis on rotating shafts and find the resonant frequencies and 5 modal shapes respectively

THEORY:

All objects have a natural frequency or set of frequencies at which they vibrate. The quality of the sound produced by a vibrating object is dependent upon the natural frequencies of the sound waves produced by the objects. Some objects tend to vibrate at a single frequency and they are often said to produce a pure tone. For example a flute tends to vibrate at a single frequency, producing a very pure tone.

PROCEDURE:

The flywheel shaft was designed in SolidWorks according to our set of dimensions.

Frequency simulation was selected

Alloy Steel material is applied to all parts

A frequency analysis was performed for 5 modes and respective outputs were obtained

RESULTS:

CONCLUSIONS:

The shown are the natural frequencies of the first 5 modal shapes. Any loading conditions resulting in vibrations of above frequencies tend to damage of the object hence frequencies above this range should be maintained
