I have a simple single rotor system between two bearings.

1) How can I get an unbalanced time series response?

2) In transient, when we apply a rotational velocity, the body doesn't rotate, but simply inertial forces act on the body. Thus a point load will be of no use. So how can I produce an unbalance?

3) The last option I have is to make the disc eccentric, but rotational velocity will not give the effect of unbalance.

I have given some eccentricity in the x-axis. As expected, the vibrations were only in the x-direction.

Don't tell about harmonic analysis. I want a time series data.

Rotational velocityaccounts for the structural effects of a part spinning at a constant rate. You can create a revolute joint and apply joint loads or apply the rotation. Also, please see if the following posts help:
