In order to facilitate the recording, displaying and computer statistical analyzing of experimental data, digitalizing modifications were made on the testing system of a simple beam Charpy impact testing machine with an incremental rotary encoder, a Siemens CPU224 PLC and ForceControl Configuration Software. Hardware and software designs were made for the testing system. The improved system can automatically record impact absorbing energy and pendulum angle, real time display and print impact energy diagrams by computer, and it can also output the measure results in EXCEL format which is convenient for data analysis and processing.

This paper designed an impact testing machine to observe the movement characteristics of particles. We simulated the rotor with different blanking frequency and different rotating speed by EDEM to explore the acceleration of the rotor. Through simulation, blanking frequency could have an impact on the rotor acceleration of testing machine, and the greater Blanking frequency was, the more obvious hanging material phenomenon was. Increasing the diameter of feed inlet could ease the phenomenon of hanging material, but would decrease particles speed. Therefore, we should not only avoid the phenomenon of hanging material, but also make the particles get high speed when designing the impact testing machine.
