物理モデルを用いたスクリューコンプレッサに発生する異常の評価

A screw compressor is an important component in a factory. It works 24 hours 365days to supply air to many machines. If a screw compressor stops, whole operation in a factory stops. A screw compressor consists of many parts, i.e., bearings, screws and so on. To diagnose a compressor, effect of damage of each component by experiment or computer simulation. In this paper, we monitored several types of screw compressor and built physical models of their components by Modelica based on experimental observations. Then we showed that features of developed model well coincided with that of experiments.
