In rotordynamic simulations, rolling element bearing waviness is often accounted using
nonlinear models that are solved with a numerical integration scheme in time domain. This …

In this paper, the centerless finishing process of bearing cylindrical roller made of AISI
52100 steel using free abrasives and soft pad was investigated by the Taguchi method in …

The support structures of a rotating machine affect its overall dynamic behavior. The stiffness
of the support structures often differs at the actual sites compared to the test rigs, which leads …

In industrial processes, large rotors are commonly operated below the critical speed, where
bearings can be an important source of subcritical vibration. This paper presents a complete …
