摘要
本文讨论了带裂纹悬臂管轴的固有频率相对变化率(RFV)的计算方法,通过分析RFV与阶数、裂纹位置和裂纹深度之间的关系。提出了用RFV-阶数关系型谱识别裂纹位置,及用综合数值计算和实验识别裂纹深度的方法。
This paper discussed the calculation method on rate of frequency variation (RFV)of cantilever pipe with transverse crack. Provided the methods that cracked location is diagnosed by RFV mode number typical spectrum and cracked depth is diagnosed by synthesis numerical calculation and expe riment, via research of relations among RFV, mode number, cracked location and depth.
