振動騒音におけるモデル化と実験解析技術

摘要

実験計測に基づく解析手法は，CAE技術の発展に呼応して，高度化，大規模化等が大きく発展すると期待している.特に，非接触計測による情報量の拡大，処理の自動化や診断までを含めた知能化技術等，さらに進んだ計測のあり方についても今後に大いに期待したい.%Noise and vibration analysis techniques are essential to designing comfortable cars which achieves both weight reduction and reduction of noise and vibration. There are a variety of methods in experimental analysis techniques, e.g. modal parameter identification, operational analysis, transfer path analysis, prediction of structural modification. However, experimental analysis techniques are expected to develop much more than current status so as to correspond to the development of computer simulation techniques. This article introduces the latest research topics of experimental measurement analysis and prospects the future development.
