The Impacts of Unbalance on the Start-up Dynamics of Flexibly Mounted Rotors

Abstract

The paper deals with the impacts of unbalance on the start-up behaviour of flexibly mounted rotors with viscous damping. It provides an overview of the dimensionless parameters describing the system in question as well as the properties determining the influence of various degrees of static unbalance on the system start-up behaviour for different driving torque scenarios, such as transient-state and steady-state differences as opposed to balanced rotors, vibration-induced power losses, etc.
