Frequency Analysis of a rotating shaft
Aim: To find the critical frequencies of the rotating shaft in SolidWorks
Modelling:
The part obtained after modelling as per the given dimensions, and then the revolve feature is used to convert the sketch into a 3D model.
Simulation:
Bearing fixtures:
Right-click on fixtures and add the necessary bearing fixtures as shown using bearing fixture option.
Create the finest mesh for the most accurate results.
