Abstract:

An intensive investigation was made of vibration test procedures applied to certain tube types. Effort was divided into 3 tasks. Task A was concerned with fatigue tests of the tube types. Correlation studies were made of fatigue effects produced by the 96-hr fatigue test and the 3-hr fatigue es . The extent of tube degradation was evaluated in terms of measurement of tube parameters and measurement of tube noise during subjection to a standard vibbration measurements test. Task B considered evaluation vibration measurements test for the purpos of establishing a standard test. Three vibration tests were compared, 2 at fixed frequency, fixed acceleration level. Maximum tube noise was the data of the test. Test reproducibility for fixed frequency test conditions lead to the conclusion that only limited correlation could be obtained from different tests or, in fact, rep tition of the same test. In Task C, factors affecting tube noise were studied in detail. Swept sinusoidal tests and random excitation tests constant special ensity and equal energy per octave were studied. Author
