AN EXCITATION AND INSTRUMENTATION SYSTEM FOR VIBRATING PLATE STUDIES.
Abstract
The thesis presents the details of the design, construction, calibration, and operation of an excitation and dynamic deflection instrumentation system to be used in studies of vibrating plates. The system presented here is designed to excite and instrument plates with maximum dimensions of 12 inches square and a thickness of 0.5 inches over a range of frequencies from 100 cps to 500 cps. Slight modifications in the equipment would allow its use on other sizes of plates and at other frequencies. The merit in the system presented here is the fact that the deflection instrumentation attaches no mass to the plate under study. For test plates made of magnetic materials, the excitation system attaches no mass either. At worst, on non-magnetic plates, an attached mass on the order of 3 grams is all that is required. Consequently, plate parameters are little affected by the complete instrumentation system. (Author)
