In order to develop a mechatronical intelligence breaking hydraulic impactor, this paper presents a chisel anti-rebound mechanism, which could identify automatically the physical characteristics of working medium. After establishing the nonlinear mathematical model of the mechanism, a dynamic simulation has been conducted, the relationship between the chisel rebound speed and the performance of the anti-rebound mechanism has been studied systematically. So the regularity about the mechanism motion has been found out. This paper describes a experimental device of the chisel anti-rebound of hydraulic impactor. According to the data collected from the experiments, the simulation results were in good agreement with the experimental ones. A good way that realized the hydraulic impactor intelligent control has been found out.
