Abstract:
The paper concerns the analysis and research of the open hydraulic
system of the hydraulic hammer. With 1000J hydraulic hammer as a
pattern, the digital simulation and the experiment of the dynamic
characteristics of its hydraulic system are performed. The results of
theoretical analyses and experiments show that the open system has
better dynamic characteristics than the closed system.
Key words:
Hydraulic hammer Open hydraulic system Dynamic
