As one of the most immensely growing renewable energies, the wind power industry also
experiences a high failure rate and operation & maintenance cost. Therefore, the condition …

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 …

Time-varying mesh stiffness is one of the main internal excitations of gear dynamics. With
the growth of gear tooth fault, like pitting, cracking and spalling, the mesh stiffness amplitude …

The diagnosis and monitoring of surface wear are very critical for the prevention of shutdown
and even catastrophic destruction of a geared transmission system. However, the detection …

Modulation of the gear mesh vibration is a major field of research for the condition
monitoring of planetary gearboxes. The modulation creates sidebands around the gearmesh …

The gearbox vibration signal of a planetary gear set contains multiple components caused
by different excitations. Separating the gearbox vibration signal to decouple its components …

This paper proposes a new effective mesh stiffness calculation method for spur and helical
gear pairs, which is explicitly formulated by an original FE-analytical slice model for tooth …

Planetary gearboxes are widely used in equipment like helicopters and wind turbines. Sun
gear is located in the center of planetary gearbox. In most cases, sun gear shaft could hardly …

The vibration signal of the planetary gearbox shows complicated modulation sidebands no
matter the gear is normal or fault. It leads to a challenge in the fault diagnosis, especially for …

Planetary gear trains equipped in wind turbine often run under slow speed and non-
stationary load condition. The incipient gear faults in a wind turbine gearbox can hardly be …
