Study on Simulation and Arithmetic of the Hydro-Pneumatic Pile Hammer

Firstly, analyzing the hammerhead parameters of the hydro-pneumatic pile hammer, and then, combining the realities and taking the wave theory for base to establishing the mass-elastic model of the pile driving system, what's more, writing the programs which were used for dynamic simulation, Finally, simulating the mass-elastic model and comparing the key parameters, giving the configuration of the technological parameters to enhance the pile efficiency.
