Investigation of Load-Induced Non-Synchronous Whirl Instabilities in Rotating Machinery.

Abstract

Seven tasks are described which were designed to reach the objectives. At the time of termination of the grant, these tasks were in various stages of completion, as described in this report. Tasks 1 and 2: Experimental Verification of 'Torquewhirl'; Task 3: Measurement of the Alford Force; Task 4: Comparison of Test Data with Theory; Task 5: Inclusion of a More General Shaft Flexibility in the 'Torquewhirl' Theory; Task 6: Derivation of the Linearized Stiffness Damping, and Cross-Coupling for Use in a Computer Stability Analysis; and Task 7: Load-Dependent Stability Predictions for a Machine of Realistic Complexity.
