| 摘 要： | 为对结构中的振动波传播,特别是遇到阻隔质量时的传播规律进行研究.首先介绍振动波的产生、传播和表述方法,然后利用波动理论,分析振动波在传播过程中遇到阻隔质量时的透射、反射规律.最后得到隔振质量对板结构中振动波的隔振度的表达式,并且推导出阻隔质量的隔振度随着振动波频率,以及随着阻隔质量的高度h的变化规律.

| Abstract: | Transmitting laws of structure vibration wave is analyzed in this paper, which blocked by isolation beam is specially analyzed. At first, the produce, transmitting and expression of vibration wave are introduced. Then transmission and reflect laws of vibration wave blocked by isolating beam with the theory of wave are analyzed. At last, the expression of quantity of vibration insulation amounts is deduced, which is changed with vibration wave frequency and altitude of isolating beam. |
