Abstract

This paper deals with the simulation of the working behaviour of a hydraulic breaker. A detailed parameterised model was realized in order to simulate physical phenomena occurring during the functioning of the machine. An appreciable agreement between experimental and theoretical pressure and frequency encouraged about the quality of the model. The dynamic behaviour of the moving masses was presented and thoroughly discussed. As a special remark, it is to be highlighted that the theoretical results suggested by the model came out not to vary if the real waveform concerning input flow rate is replaced with its average.
