要旨 : 当社では,1970 年代後半より振動法による回転機械診断技術の導入,開発を積極的に進め てきた。回転機械診断エキスパートシステムは,マニュアル,オフラインおよびオンライ ン診断のすべてに適用でき,操作も容易で,すでに16 システムが稼動している。自動診断 機能を有するオンライン診断システムは,自動報告書作成機能を持ち,マン・マシンイン ターフェースの改善を図っている。さらに,ホストコンピュータとリンケージする振動計 付ハンディターミナルの開発は,測定範囲の拡大と点検作業の大幅な効率化につながった。 これらのシステム化,インテリジェント化の結果,ダウンタイムの低減やオーバーホール 周期の延長など著しい効果が得られた。 Synopsis :

Ever since the latter half of the 1970s, Kawasaki Steel has aggressively promoted the development and introduction of the diagnosis technique of rotating machines. Manual, off-line and on-line diagnoses are applicable to the easy-to-operate expert system for rotating machines, and 16 systems are now in operation. The on-line diagnosis system furnished with the automatic diagnosis function is also equipped with the automatic report making function with a view to improving the man-machine interface. Further, the development of the handy-terminal with a vibration meter which is linked to a host computer has led to the expansion of the measuring range as well as substantial improvement of efficiency. The systematization of techniques and development of intelligent systems have produced an excellent effect on reducing downtime and extending overhaul cycles.
