Critical Speed of a Dual Rotor System

Application ID: 78211

Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing.

In this example, eigenfrequency analysis is performed for such a dual-rotor system in order to determine the critical speed. Cross-exciting vibrations through multi-spool bearings makes the dynamic behavior of one shaft dependent on the dynamic behavior of the other.
