| Abstract: | A hydraulic exciting system with a wave exciter has been constructed in order to study the hydraulic vibration law.The system consists of an oil source,wave-exciter and oil cylinder,and is controlled by a wave-exciter.The working principle of the hydraulic exciting system and wave exciter has been analyzed,and its excitation process has been illustrated.The law of every pipe’s pressure fluctuation of the system is obtained by experiment.The theoretical analysis and experimental data prove that the pipeline pressure periodically changes and the pipeline pressure fluctuation frequency is independently controlled by the excitation frequency of the wave-exciter.Every pipeline’s pressure wave is produced by system flow fluctuation and water hammer coupling.The pressure fluctuation rules of the system provide a theoretical basis for the study of the associated liberation system. |
