Abstract

Equations of motion and continuity equations of a hydraulic breaker are derived. Hydraulic pressures are defined with 6 state variables corresponding to 6 control volumes. Impact analysis procedure of the piston and chisel is developed based on the finite element nodal displacement description. Computer simulation is performed with given design parameters and the results are compared with experimental results.
