摘要
从质量引起的阻抗失配的原理出发,利用波动理论分析了在板中嵌入一块方钢所引起的对振动波传播的阻碍作用,并且通过NASTRAN有限元软件进行了模拟计算,检验了方钢结构的隔振效果.
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.
