The large load capacity, compact size and high-power density have made planetary gearboxes widely applied in heavy machinery such as wind turbines. Although well designed, planetary gearboxes are vulnerable to fatigue crack because of harsh working e

In this paper, we consider the problem of assigning a given reliability improvement target of an existing series system to its constituent subsystems in view of the failure risk and improvement cost. Previous research has solved this problem by devel

Failure mode and effects analysis (FMEA) is a structured method used during a given stage of the system life cycle to understand all probable failure modes and the effects of their occurrences. The risk priority number (RPN) is calculated in FMEA to

Tooth pitting is a common failure mode of a gearbox. Many researchers investigated dynamic properties of a gearbox with localized pitting damage on a single gear tooth. The dynamic properties of a gearbox with pitting distributed over multiple teeth

Time Limited Dispatch (TLD) allows a degraded redundant system to operate for a limited length of time before it is sent for repair. Existing TLD analysis methods do not consider dispatch reliability requirement as a constraint, thus unacceptable fli

For systems with functionally exchangeable components, those components may work in different health states after operating for a period due to distinct working loads or external environment. To explore the full use of all components and extend the o
