一种运动物体的气固摩擦起电试验方法及装置

By constructing a gas triboelectric model and using a non-contact measurement method, the problem of measuring the charge generated by gas-solid friction under different conditions in aircraft was solved. The influence of motion speed, effective friction area and ambient air pressure on the amount of charge was revealed, providing theoretical support for electrostatic protection of aircraft.

Abstract

本发明公开了一种运动物体的气固摩擦起电试验方法及装置，涉及摩擦起电测量技术领域，包括以下步骤：基于麦克斯韦速度分布规律构建样品小球在内置法拉第笼的手套箱内自由跌落过程中的样品小球与气体摩擦起电模型；对样品小球进行标准化预处理，以去除其表面残留电荷；对内置法拉第笼的手套箱内进行空气置换，直至其内气压及环境参数符合试验要求，并确定样品小球的直径范围和跌落高度；对静电荷信号进行滤波处理，读取不同跌落高度时的样品小球静电荷量，用于确定样品小球在内置法拉第笼的手套箱自由跌落过程中所增加的电荷量；实现通过非接触式方式，测量在物体运动速度、有效摩擦面积、环境气压因素影响下的运动物体气固摩擦起电量。
