Investigating Effects of Vibrations and Surface Waviness on Dry Sliding Wear and Friction

将进行一项实验研究，以确定在干滑动接触中接触振动对摩擦和磨损的影响，并绘制最佳振幅和频率条件图，以在给定条件下给出最小的磨损和/或摩擦。振动将由外部致动器施加，或由工程表面粗糙度引起的滑动表面产生。研究结果将用于开发和验证该效果的模型，并为电刷等组件的操作条件的设计选择奠定基础。

An experimental study will be made to determine the effects of contact vibrations on friction and wear in dry sliding contact and to develop maps of optimal amplitude and frequency conditions to give minimal wear and/or friction for given conditions. Vibrations will be imposed from external actuators or generated by the sliding surfaces due to engineered surface roughness. The results will be used to develop and validate a model for the effect and to form the basis for design selection of operating conditions for components such as electrical brushes.
