Abstract
In recent years, the number of helicopters with vibration monitoring equipment, which is called Health and Usage Monitoring System, has increased around the world. The vibration monitoring is intended for condition based maintenance which is economically advantageous maintenance method. First SH-60K helicopter with vibration monitoring equipment was delivered for Japan Maritime Self-Defense Force in 2005. Mahalanobis Taguchi System (MTS) is applied to vibration monitoring method for helicopter's transmission. MTS is a method which evaluates the difference between a target signal and normal signal by Mahalanobis Distance. This paper shows an approach of SH-60K helicopter for vibration monitoring and experimental results intended to evaluate MTS.
