Different models of a hammering system with impact energy transfer in a closed chamber filled with fluid are analyzed. It is proved that the piston and the tool in the model can be represented by solid nondeformable bodies while the fluid-filled chamber by an inertialess elastic element. Based on the analyses, the forces in the fluid-filled chamber and at the tool-and-rock contact, as well as the impact energy transfer ratio are related with the chamber parameters and the rock-tool contact stiffness. The algorithm is proposed to calculate such system dynamics with regard to fluid leaks, variable viscosity and bulk modulus of elasticity.
