摘要
对复合材料无限大板中弯曲波的频散特性、结构和声波之间的交互作用进行了理论研究 .得到了该类结构中弯曲波所激发的声速和声压的解析表达式 ,揭示了层板中弯曲波和其传播方向对声波的影响 .为噪声控制和无损检测提供了理论依据 .
The theoretical study on interaction between infinite composite plate and acoustic radiation is present.The dispersive characteristic on bending wave of composites plate is studied. The analytical results of acoustic speed and acoustic pressure is presented. The effect on acoustic wave excitated by composite bending wave transmitting directions is discovered. It can be useful to noise control and NDT evaluation.
