Frequency Analysis of a rotating shaft

Objective:

To perform frequency analysis on the rotating shaft and to determine the made shapes and resonant frequencies of the model.

Introduction:

Frequency analysis is carried out to determine the natural frequencies of a part. Frequency analysis in SOLIDWORKS Simulation allows us to efficiently investigate the resonant frequencies of a design. This analysis type helps us ensure that the natural modes of vibration are well away from environmental forcing frequencies that a design might encounter during service.
