The aim of this work is to propose a novel approach for the estimation of the Instantaneous
Angular Speed (IAS) of rotating machines from vibration measurements. This work is …

The present paper describes a ball bearing model for transmission monitoring and adapted
to non-stationary operating conditions. The model considers axial forces in bearing as well …

In current studies of dynamics of the defective bearing, the lumped-parameter model of the
rolling element bearing is widely used, which is a simplified bearing vibration model …

This work has been developed within the framework of non-stationary rotating machinery
surveillance with emphasis on the detection of rolling element bearing defects. The …

This paper proposes a tool for the generation of synthetic mechanical signatures of faulted
gears and bearings in non-stationary conditions. Synthetic signals are commonly used to …

Instantaneous angular speed (IAS) analysis has been presented as an advantageous tool
for non-stationary machinery surveillance. The physical analysis indicates that the …

This study presents a combined feedback–feedforward adaptive regulator applied to an
active vibration control tool holder platform to contain the effect of machining vibrations. The …

Nowadays, condition monitoring and diagnosis of rotating machines, especially in energy
production, are among the major societal and scientific problems for improving machine …

In the field of condition monitoring the availability of a real test-bench is not so common.
Furthermore, the early validation of a new diagnostic technique on a proper simulated signal …

The estimation of the Instantaneous Angular Speed (IAS) has in recent years attracted a
growing interest in the diagnostics of rotating machines. Measurement of the IAS can be …
