How to model an unbalanced shaft and perform a rotor dynamics analysis

Adrunodro

I want to analyze a shaft with different unbalanced mass. I want to get the deflexión of the mass for different rotational speeds and unbalance. Is this possible?

Adrunodro,

Are you using OptiStruct for Rotordynamics.

You can use UNBALNC to define unbalanced loading during rotor dynamic analysis.

Please refer to this: UNBALNC (altair.com)

You can also refer to this example for using the UNBALNC: OS-E: 6010 Rotor Unbalance using Modal Frequency Response Analysis (altair.com)

Many thanks Viraj. I will test it when I got the time
