概要

• 論文の詳細を見る

• This paper proposes a method to do condition diagnosis about non stationary signal generated by operating rotary machineries which are bearing, gear, rotor and so on. Especially, a signal processing technique in order to eliminate slight non stationary noises including operating sound is described by adopting locally stationary AR model [1] a kind of system identification. The effectiveness of this modeling has been identified by numerical simulation based on a rotary simulator device on a failure rolling bearing.
