Model Description
This example consists of two coaxial rotors modeled using 1D elements. One end of each
rotor is constrained, the same end is attached to stator using rigid elements and on the
other end is attached to the stator through spring and damper elements. Static loading
condition due to centrifugal force is applied to the rotors also relative spin between the
two rotors are defined. Synchronous and Asynchronous analysis are performed at different
maximum rotor speeds.
