摘要/Abstract

摘要：

针对现有摩擦起电研究缺乏规范化试验支持的问题,自主研发一套适用于摩擦起电试验的摩擦-电学性能测试系统.通过模块化设计和系统集成,依次完成加载、运动和测控模块的设计,并开发LabVIEW测控软件.通过设置缓冲弹簧,优化加载结构,实现小载荷条件下的平稳加载,同时对上、下试样进行绝缘处理,实现对微电流的精准测量.通过对标测试和摩擦起电试验,验证测试系统的可靠性,并分析铜-铝界面转移电荷量的变化情况,初步确定转移电荷量与载荷的线性关系.研究结果有助于摩擦-电学测试的规范化.

Abstract:

In view of the lack of standardized test support for existing triboelectric research, a system suitable for the triboelectric performance test was independently developed. Through modular design and system integration, the three modules of loading, motion, and measurement control were designed in turn. The LabVIEW measurement control software was developed. By adding buffer springs and optimizing the loading structure, the stable loading under small load conditions was achieved. In addition, based on the insulation treatment of the upper and lower samples, the accurate measurement of micro currents was achieved. The reliability of the test system was verified by benchmarking test and friction electrification test, and the transferred charge of Cu-Al friction interface was analyzed. Moreover, the linear relationship between transferred charge and load was preliminarily determined. The results are beneficial to the standardization of tribo-electrical testing.

Key words: triboelectric, test system, design and optimization, experimental verification
