| Abstract: | On the principle of impedance mismatching, the phenomenon that the transmit of vibration wave (structural noise) is obstructed by an embeded quadrate steel beam is explained. The analog calculation is made using the finite element software--NASTRAN. The vibration isolation of quadrate steel beam is proven effective. |
