Gearbox plays a vital role in a wide range of mechanical power transmission systems in
many industrial applications, including wind turbines, vehicles, mining and material handling …

Gearbox is widely used in industrial and military applications. Due to high service load,
harsh operating conditions or inevitable fatigue, faults may develop in gears. If the gear …

Despite the recent advances of intelligent data-driven fault diagnosis methods on rotating
machines, balanced training data for different machine health conditions are assumed in …

Rotating machinery fault diagnosis problems have been well-addressed when sufficient
supervised data of the tested machine are available using the latest data-driven methods …

In the past years, deep learning-based machinery fault diagnosis methods have been
successfully developed, and the basic diagnostic problems have been well addressed …

Rotor-roller bearing-housing systems (RBHSs) are widely utilized in many industrial
machinery, such as aero-engines, high speed trains, wind turbine, etc. A clearly …

Considering the realistic spalling morphology obtained from the fatigue experiment, a novel
dynamic model for spalled gear pairs is established in this paper. Loaded tooth contact …

In industrial rotating machinery, the transient signal usually corresponds to the failure of a
primary element, such as a bearing or gear. However, faced with the complexity and …

Based on the finite element theory and the loaded tooth contact analysis, an analytical-finite-
element model considering the complex foundation types and the crack propagation paths is …

Gears are prone to failures, which are difficult to detect in the early stage. In this study, the
time-varying mesh stiffness of gears teeth with different crack lengths is calculated, and the …
