Abstract: Order tracking (OT) is an effective fault diagnosis method for rotating machinery under variable speed conditions. Accurate instantaneous frequency (IF) is the premise of this method. In ...

Abstract: Rapid power and torque fluctuations in time-varying conditions increase the fatigue load and failure rate of wind turbine (WT) gearboxes. In this study, an optimal power control method is ...

Imagine a small child trying to push a full-size adult in a shopping cart. It’s possible to get the cart moving (barely), but it would be very hard to start or stop. Steering could be disastrous—the ...

Modern machining and design advancements have made tight backlash control and high efficiency achievable in gear systems. Proper system integration, including load and control considerations, is ...
