Due to planetary movement of planet gears. the vibration signal perceived by a stationary sensor is modulated and difficult to diagnose. This paper proposed a vibration separation methodology compensated by a time-varying transfer function (TVTF-VS). which is a further development of the vibration separation (VS) method in the diagnosis of non-hunting tooth planetary gearboxes. https://www.animationbengal.com/?w=super-price-johnny-cash-at-folsom-prison-fashion-great-buy
