| Abstract(J) | エンジンの実稼動振動データから直接固有モードを抽出する技術の提案をした。エンジン振動の特徴を考慮し、次数トラッキング振動データをもちいることで、モード抽出精度が向上した。本手法の精度を、加振による擬似トラッキング解析と、実際のエンジン振動で検証し、精度良くモードが抽出できることを確認した。 Translation |
| Abstract(E) | Modal analysis using engine operational condition data is proposed. Order tracking vibration data is used in the subspace method, taking the features of engine vibration into consideration, and the identification of modal parameters is enhanced. In the excitation test, the results are compared with the modal analysis using the transfer function, and it is confirmed that similar modes are obtained. By applying this method to actual engine vibration, the chain cover modes of diesel engine are identified, and it is confirmed that the identification of modes using order tracking vibration data is enhanced compared to using average spectrum and compared to the conventional operational deflection shape. |
