S-transform Analysis on Pulsating Water Pressure Acting on the Stop Log Gate

摘要：

　　The vibration of sluice gate may lead to the damage of the hydraulic structure,based on the S-transform,the frequency and the phase distribution of the pulsating water pressure.The results show that as the water level increases,the frequency of the pulsating water pressure is small,the pulsating power acting on the bottom of the gate is decreasing,the components of frequency are rich,the power is wide,although the amplitude of frequency is decreasing,the whole power of pulsation is not changed; there is an obvious wave about the phase as the time changes,the phase distribution map is symmetry and periodically changes,and the velocity of wave may increase as the frequency increases.
