Experimental Research of Impact Force Distribution on Rigid Wall by High Pressure Waterjet
For exploring the distribution of impact force on rigid wall by pure waterjet and abrasive jet, the distribution of impact force with waterjet cutting angle at a 90° angle to the rigid wall, and effects on the impact force by the distance of nozzle from the rigid wall and water pressure available for the waterjet system were all tested with a specific force?measurement table, and the intensifying effect achieved by abrasive jetting was also analyzed. It is found that impact force of waterjet decreases rapidly with the increasing of radial distance, as a non?monotonically decreasing step function, connecting the central position of workbench and following a non?monotonic negative exponential decreasing rule. With the same distance between the nozzle and rigid wall for both pure waterjet and abrasive jet, the central position ( with the highest pressure) correlates positively with the system pressure.
