This report presents data obtained during prototype tests concerned with the vibration of the 50- by 55-ft spillway tainter gates at Barkley Dam. The gates vibrate during flow passage in which the gate lip is submerged by high tailwater. Field tests were conducted on two of the gates during high tailwater. Three pressure transducers were placed near the lip of the gate. In addition 14 accelerometers were attached at preselected locations on the gate. The second gate was instrumented with five accelerometers only for a limited data comparison. Data reduction indicated that many components vibrate at the same frequency as the gate lip pressure fluctuations. Computations and ring tests indicate that this frequency approaches at least one component's natural frequency. The gate seal at the lip was removed and the test repeated under identical conditions. The measured vibrations were all dramatically reduced. By varying the opening of the gates, under identical conditions, it was found that vibration severity decreased with increasing tailwater submergence. Remedial measures in design and operation of the gates were recommended.
