Nowadays, condition-based maintenance (CBM) and fault diagnosis (FD) of rotating
machinery (RM) has a vital role in the modern industrial world. However, the remaining …

Phenomena of friction, wear, and noise in mechanical contacts are particularly important in
the field of tribomechanics but equally complex if one wants to represent their exact …

The sound quality of vehicle interior noise strongly influences passengers' psychological
and physiological perceptions. To predict the sound quality of interior noise, a vehicle road …

Frictional vibration and noise usually cause machining error and noise pollution. Stick–slip
plays an important role in generating frictional vibration and noise. This study characterized …

Many numerical simulations have been dedicated to the brake squeal prediction by
considering the predominant influence of the frictional interface between the pads lining and …

Dry friction appears at the contact interface between two surfaces and is the source of stick-
slip vibrations. Instead of being a negative factor, dry friction is essential for vibration-driven …

In this work, disc surfaces with two kinds of groove configurations are tested in a pad-on-disc
system. The experimental results show that cutting 45° grooves on the disc surface can …

The vibration-driven locomotion system subject to the Coulomb dry friction is a typical multi-
degree-of-freedom piecewise-smooth dynamical system with rigid-body displacement …

The occurrence, growth, limit cycle amplitude and mitigation of brake squeal noise are
investigated using a predictive analytical coupled modal model. The model is developed to …

An accelerogram of the instantaneous phase of signal components referred to as an
instantaneous frequency rate spectrogram (IFRS) is presented as a joint time-frequency …
