Abstract: Abstract Fault diagnosis of planetary gearboxes under variable-speed conditions is a challenging task since the vibration signals are non-stationary and have more complicated characteristic components due to the complex gearbox configuration. Effectively identifying and extracting… read more here.

DOI: 10.3390/ma10060675
Abstract: Varying speed conditions bring a huge challenge to incipient fault detection of rolling element bearings because both the change of speed and faults could lead to the amplitude fluctuation of vibration signals. Effective detection methods… read more here.
