| Abstract(E) | This study reports the development of a method for calculating an Order-based FRF using CAE analysis with a finite element model (FEM) for enhancing the sound quality of engine combustion noise. An FEM was created from a power plant model equivalent to a bench vibration test, and it was confirmed that an Order-based FRF similar to the experiment could be calculated. In order to simplify the analysis model, verification was carried out, so the main motion system model was omitted and a method of inputting the excitation force to the main bearing was considered. As a result, it was found that an Order-based FRF equivalent to the actual machine experiment could be calculated with only the power plant structure model. By using the CAE analysis method constructed in this study to calculate the Order-based FRF, it is possible to identify the frequency band and mode of concern for sound quality deterioration and to consider countermeasures at the pre-prototype stage. |
