- •
It is shown how the stability changes with the support stiffness and damping.
- •
The stability can be significantly improved by viscoelastic supports.
- •
The optimal groove configuration changes with support conditions.
- •
Stability maps for the bearing system are obtained.
- •
Behaviors of journal and bearing center are simulated.
