Abstract: The blow process of anvil-less hydraulic hammer is analyzed. The mathematical models are formed theoretically, and the digital simulation is performed by means of computer. The displacement and the velocities of two Cups and the fluid pressure in cylinders are obtained by means of simulation. The analysis and the research are performed by the comparison with the result of experiment.

Key words: Digital simulation, Experiment, Hydraulic hammer
