Abstract：

The structure, working principle and working process of the hydraulicair hammer were described. The mechanics model of counterblow hydraulicair hammer in the working process was established by force analysis and then the vibration simulation of hammer body with MATLAB based on SIMULINK model coming from mechanics model was carried out to obtain the vibration curves of different gas pressures in working chamber, gas pressures in supporting cylinder and equivalent stiffness. The effects of gas pressure in working chamber,gas pressure in supporting cylinder and equivalent stiffness on the vibration of hammer body and its excitation of foundation were analyzed, which provides the basis for optimization design of hydraulicair hammer.
