dc.description | Abstract: This report presents data obtained during prototype tests concerned with the vibration of a 106-3/4-in.-diam Howell-Bunger valve at Summersville Dam, Gauley River, W. Va . Prototype measurements include both dynamic and time-averaged values of pressures in the flow and strain at locations on the valve structure. Transverse, vertical, and peripheral accelerations were measured at the downstream end of the valve cone. The data were recorded simultaneously on analog magnetic tape and on oscillograph charts. Data reduction was by scaling the oscillograph traces and by using electronic analog equipment to perform linear spectral density, amplitude density, and cross-correlation analyses on the magnetic tape data. The results include information on (a) discharge characteristics of the Summersville outlet works, (b) evaluation of the nature of the pressure fluctuations in the flow, and (c) evaluation of the nature of the vibration (including approximate natural frequency values) of the valve at the strain gage and accelerometer locations. The primary conclusion regarding the vibration is that the significant strain fluctuations are caused by low-frequency pressure fluctuations buffeting the valve. These frequencies are well below the natural frequencies of the structure. | - |
