Abstract:

A simulated testing system of electrostatic dynamic （ESD） potential is designed based on the non-contact detection of electrostatic potential and the virtual instrument technology. By using the designed system, the variation of electrostatic potential in the simulated operation process can be tracked in real time, and the electrostatic hidden trouble can be effectively analyzed. The system is then applied to an ESD project, and a regressive model for the electrostatic potential as a function of the friction pressure, the separation speed, friction number and the humidity in dangerous goods processing is obtained. Moreover, an interactive analysis of the above-mentioned parameters is performed. The results indicate that there is no obvious interactive effect among the parameters, and that the parameters affect the electrostatic potential in the order of friction material 〉 humidity 〉 friction pressure 〉 friction number 〉 separation speed.
