| Abstract: | The paper calculates and analyses the problem of vibration and noise of subway gear box with the combination of structural FEM and acoustic FEM. Modal frequency and vibration response of the gear box are computed by structural FEM with a 3-D FE model. Then acoustic radiative pressure level is computed with a 3-D FE acoustic-field model and bounary conditions imported from the result of vibration response by infinite FEM. |
