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.
