| Abstract: | An acoustic radiation model for an I.C. engine cylinder block was set up based on the FEMand BEM, and the corresponding computing program was compiled. The measuring results ofcomplex acoustic miensity show that the model and computing results are reliable. It is thefundation of low noise engine design. |
