Research of hydraulic impactor with self-adaptive intelligent buffer

After analyzing the hydraulic impactor at home and abroad, a new control strategy of self-adaptive buffer has brought forward and a vibration mechanics model of buffer has established in this paper. We also designed a control system of self-adaptive buffer of hydraulic breaker which was controlled by single-chip computer. At the same time, we set up a simulink model of microcomputer control system of self-adaptive buffer, performed a digital computer simulation on dynamic characteristics of the system and finally proved that microcomputer control system can adjust damping by detecting acceleration sensor for controlling the working state of the hydraulic breaker. All these provided a theoretical basis and technical guidance for development of an intelligent hydraulic impactor.
