RT Journal Article T1 An Artificial Intelligence Approach for Gears Diagnostics in AUVs A1 Nicolas Marichal, Graciliano A1 Del Castillo Zas, María Lourdes A1 López López, Jesús A1 Padrón, Isidro A1 Artes Gomez, Mariano AB In this paper, an intelligent scheme for detecting incipient defects in spur gears is presented. In fact, the study has been undertaken to determine these defects in a single propeller system of a small-sized unmanned helicopter. It is important to remark that although the study focused on this particular system, the obtained results could be extended to other systems known as AUVs (Autonomous Unmanned Vehicles), where the usage of polymer gears in the vehicle transmission is frequent. Few studies have been carried out on these kinds of gears. In this paper, an experimental platform has been adapted for the study and several samples have been prepared. Moreover, several vibration signals have been measured and their time-frequency characteristics have been taken as inputs to the diagnostic system. In fact, a diagnostic system based on an artificial intelligence strategy has been devised.
