Full text not available from this repository.Abstract
A simple method for designing models of complex shaft configurations for advanced fluid powered systems is presented. Using this method, a highly complex rotor-bearing configuration can be suitably scaled down to be tested for performance at the laboratory levels, keeping the same nondimensional speed and undamped/damped mode shapes between the prototype and the model. The modeling procedure takes into account the coupling, gyroscopic effects, external damping provided by fluid film dampers, and nonshaft masses that are likely to be present in the prototype. An example showing the similarity in the first two mode shapes and the critical speeds between the prototype and the model is presented.
