Аннотация: Reliability of collector rings throughout their service role plays a key role in the performance of power supply systems of various equipment and largely depends on strength and reliability of all of their components, particularly contact rings. One of the most important features of collector rings is their contact resistance. It iПоказать полностьюs usually decreased by using non-ferrous and precious metals and a simultaneous increase of tracking force. However, this approach leads to a sharp increase of stresses within the contact rings. These stresses may even reach or exceed the yield limit of the material and cause its eventual destruction. Nonetheless, performance of contact rings outside the yield limit is possible with using the low-cyclic fatigue area of the fatigue curve. This paper proposes the respective methods of analytical calculation of contact rings’ fatigue and probability of their no-failure performance in plastic state. © 2020, Springer Nature Switzerland AG.
