Комбінований трибологічний вплив пар та наноамплітудних коливань на робочі поверхні деталей машин

Abstract

речовини (ПАР) та наноамплітудних вібрацій на трибологічні характеристики робочих поверхонь деталей машин.

(SAA) and nano-amplitude vibrations on the tribological characteristics of working surfaces of machine parts. A mathematical model of dynamic contact has been developed, and the change in friction coefficient under various vibration parameters has been estimated. It is established that at a vibration amplitude A ≈ 30 nm and frequency f ≈ 50 kHz, the friction coefficient can be reduced by 2–3 times. The proposed approach can be applied in sliding bearings, gear transmissions, machine tool guideways, and internal combustion engine assemblies.
