VIBRATION TRANSMISSION STUDIES OF FLEXIBLE PIPE CONNECTIONS

Abstract

The results of studies of vibration transmission on three sizes of pressurized and unpressurized flexible pipe connections are presented. The connections include Dacron-lined and steel-braided hoses in 'dog-leg' configurations and Electric Boat flexible pipe couplings in three-planar configurations. Results showed that, generally, the Dacron-lined hoses exhibited lower vibration transmission characteristics than did the steel- braided hoses and Electric Boat flexible couplings. However, the Dacron-lined hoses showed a larger increase in vibration transmission between 20 and 800 hertz when pressurized, than did the other types of flexible connections in the same frequency range. Results also showed that little difference existed between the magnitudes of transfer impedance for the three sizes of unpressurized Dacron-lined flexible hose. (Author)
