Comparison of gear diagnostic methods used in the space industry
The basic method for examining the condition of gears is the vibroacoustic method. This method is widely used around the world for diagnostic purposes. However, it is not always possible to use it. This especially applies to mechanisms operating ultimately in space. Harsh working conditions, the presence of the vacuum of space, radiation, reactive oxygen ions and many other factors make diagnostics in this environment much more difficult. This article compares vibroacoustic, electrical, optical and other methods in terms of their potential application for diagnostic purposes of gears used in the space industry.
