Abstract In some industrial devices, the use of a sliding contact to transmit power currents or communications signals is required. The physical and, in particular, tribological understanding of these electromechanical systems is therefore a major issue. Thus, this article reports a theoretical and numerical study accounting for the mechanical influences about the electric transport properties of a sliding metallic dry contact and their variations with sliding speed and contact load. These variations are characterized by analyzing the voltage noise across the contact during sliding. Results are compared to experimental data and show good agreement between theory and experiments below a critical speed value. This study is part of research and development on tribology and dynamical interface monitoring.

环/线滑动接触的电响应的机械模型

摘要 在一些工业设备中，需要使用滑动触点来传输功率电流或通信信号。因此，对这些机电系统的物理和特别是摩擦学的理解是一个主要问题。因此，本文报告了一项理论和数值研究，解释了滑动金属干触点的电传输特性的机械影响及其随滑动速度和触点负载的变化。这些变化的特点是分析滑动过程中触点两端的电压噪声。结果与实验数据进行了比较，并显示出低于临界速度值的理论和实验之间的良好一致性。这项研究是摩擦学和动态界面监测研究和开发的一部分。
