Natural Frequency of torsional vibration using Abaqus software and Mechanical vibrations book
In this example, we intend to calculate the Natural Frequency of torsional vibration for disc mounted to the shaft in the Abaqus software
In this training video we first calculate the natural frequency of torsional vibration using the Analytical Solution, and in the next step , calculate the natural frequency of torsional vibration using the Abaqus Software, and in the final step, compare the results obtained from the Abaqus software with those gained from the Analytical Solution
As you observe in the picture, the Model includes Shaft and Disc. The Shaft and Disc are made of Steel
The natural frequency of torsional vibration from the Analytical Solution is equal to 48.44 Hertz
The natural frequency of torsional vibration from the Abaqus software is equal to 47.25 Hertz
As you observe, the results obtained from the Abaqus software is quite in conformity with the Analytical Solution and indicates that the problem has been simulated correctly in the Abaqus software

Why 3rd mode?

In the training video, it was said that the third mode is related to the torsional frequency, which can be determined from the shape mode, which mode is related to the torsional frequency.
