Abstract As the "heart" of the super-high pressure water jet cutter,intensifier′s running parameters control the capability of whole equipment.Differential equations with different time were found based on the Newton second law and the compressible equation of water.The numerical solutions were gained from MATLAB software.The analysis reveals that the hydraulic pressure is an important parameter and the intensifier has different moving characteristics in three different displacement time.First,the velocity increases continually with the decreasing acceleration;then the velocity decreases with the acceleration increasing;finally the velocity decreases with the acceleration decreasing.In the entire displacement,the maximum velocity is higher than the average velocity.Lastly,the results are compared with the experiment and proved to be reasonable.
