英文摘要：

On the basis of the working principle of a new hydro-pneumatic pile hammer impactor control sys- tem, we made the dynamic modeling for its impactor system piling process. Finally, each dynamic modeling is simulated and analyzed with Matlab software, and the result of simulation research is helpful for improving and optimizing key design parameters of pile hammer impactor system.
