摘要: 在非接触式静电电位检测技术的基础上,引入虚拟仪器技术,设计了静电动态电位模拟试验系统,该系统能根据需要实时记录模拟作业过程中静电电位的变化,进行静电隐患的分析.将该系统用于实际静电工程项目,模拟了危险品作业工况,得出静电电位随摩擦压力、分离速度、摩擦次数、湿度等因素变化的回归模型,并对影响静电起电的因素进行了交互性作用的研究.结果表明:在静电起电过程中各因素之间的交互作用不是很明显;各因素对于静电起电的影响作用依次为:摩擦材料〉湿度〉摩擦压力〉摩擦次数〉分离速度.

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.
