Abstract	Pulsating flow hydraulic system (PHF) which uses the vibration of oil liquid to transfer power is different from conventional hydraulic system. Because of the alternative pulsation of liquid, it's necessary to calculate the vibration characteristic such as amplitude attenuation of pulsating quantity and degree of phase lag at the output and transmission efficiency of the system exactly when the PFH system is designed. The computational expressions of key parameters such as resonance frequency of pipe, transfer matrix of pipe, load characteristic, transmission efficiency of the system are obtained by studying on the dynamic characteristics of fluid pulsation in a pipe. Base on these the parameters of a new designed PFH experiment system are calculated. The calculated value and the measured value are close and they have the same trend. The results show that the vibration characteristic and transmission efficiency of the pulsating flow hydraulic system are decided by load characteristic besides pipe characteristic. Load characteristic design is critical to the design of a PFH system. The research results provide a reliable theoretical basis for the design of the PFH machinery of the same type.
