摘要
本文采用自动数据采集及FFT技术研究应力波的弥散与衰减特性。用铝杆的应力波实验结果与理论解的比较,验证所掌握方法的可靠性。通过实验工作,对应力波实验技术及数据处理中的若干问题作了探讨。
Dispersion and attenuation characteristics of stress waves were studied by means of the automatic data collection and FFT technique. Test results of alluminium were compared with the theoretical results to verify the reliabitity of the methods adopted. Based on our experiments, several problems on the test technique of stress waves and data treatment were studied.
