摘要
Lamb波计算是板波声发射技术中的重要理论基础。介绍了几种板波声发射技术中的Lamb波计算方法,通过计算机代码采用不同方法计算了远场工况下的波形并与文献实验结果进行对比,分析其适用特点。选取合适计算方法应用于模拟空间碎片撞击声发射信号计算中,展示了其在此领域的应用前景。
Lamb wave calculation is of importance as theoretical foundation for plate wave acoustic emission technique. Several main methods for calculating Lamb wave and their applications in plate wave acoustic emission study were presented. With codes of these methods the waveforms in far field were determined and compared with those from experiments. The methods were discussed and their usages were presented .
