The article presents the results of theoretical and experimental research of acoustic emission of friction units during rolling-sliding friction contact. The purpose of this study is the development of a method of accelerated assessment of contact fatigue strength with the application of acoustic emission during friction contact. The application of acoustic emission method reveals per... https://www.bekindtopets.com/discount-Zippy-Paws-Lightweight-Adventure-Backpack-Graphite-hot-value/
