Investigating the Wear Mechanism in Electrical Brushes Associated with Thermoelastic Instability

对整体碳电刷的磨损进行了研究。将电刷磨损颗粒喷射理论的解析模型与实验结果进行比较。实验装置将使观察接触区域热点的发展和运动成为可能，这些热点是由于摩擦加热和电流从电刷表面到匹配表面的加热而产生的。将确定一些测试参数的影响，并将结果用于验证和改进模型。

The wear of monolithic carbon electrical brushes will be studied. Analytical modeling of the particle ejection theory of brush wear will be compared with experimentally obtained results. The experimental apparatus will make it possible to observe the development and movement of hot spots in the contact area, generated due to both frictional heating and heating from the electrical current passing from the brush surface to the matching surface. The effect of a number of test parameneters will be determined and the results used to validate and improve the model.
