A technique of hydraulic pressure pulse series generation by means of oil hammer is discussed. It is confirmed experimentally that a stable pressure pulse series can be obtained in a pipe, one end of which is attached to a rotary valve which controls a flow to be periodically off and on. The results of numerical calculation show good agreement with the experimental results. The pulse pressure is amplified by a booster piston, and the amplified pressure in the booster chamber runs up to about 140MPa at a frequency of 15.2Hz. It is expected that the frequency of the pulse series can be heightened by adopting a shorter pipe and the pulse pressure can be raised by increasing the amplifing ratio of the booster piston. The technique of pressure pulse generation applying an oil hammer is practical enough for generating a high frequency and high pressure pulse series.
