摘要

In this study, experiments were conducted to investigate the effects of modulation position on the impact performance (axial impact pressure, erosion radius, and erosion depth) of mechanically modulated pulsed water jet (MPWJ). The frequency of MPWJ was kept constant at 20 Hz, and the supply pressures were varied from 10 MPa to 25 MPa. The results showed that both the disc-to-nozzle distance and disc-to-target distance influenced the impact pressures of MPWJ. There was an optimal ratio of disc-to-nozzle distance to disc-to-target distance for achieving maximum impact pressure. Compared with traditional jet, there were extra radial grooves on the eroded samples. Under the same standoff distance, the reduction of disc-to-nozzle distance caused an increase in the radius of erosion crater. The depth of the erosion crater increased first and then decreased with the increasing ratio of disc-to-nozzle distance to disc-to-target distance. The results of this study provide useful information to determine appropriate parameters to improve the processing capability and coverage of MPWJ during material processing.
