In this article, we describe a method of the roller bearing lubrication regime prediction. It uses a mathematical model of the bearing based on the standard ISO/TS 16281 to obtain the external load distribution over the rolling elements. We consider

This paper focuses on modeling the time-varying stiffness of spur gearings, which in dynamic models of transmission systems acts as an important element of the internal excitation of the dynamic system. Here are introduced ways to approach the modeli

Vibration monitoring of bearings is a well-established diagnostic method. It is not very responsive to detection of a lubrication film. In this study we experimentally explore a method based on the Surface Acoustic Waves (SAW). It uses a sensitivity
