摘要
通过单级叶轮的激振试验表明,断叶片后在功率谱中发现有十分明显的与叶片数有关的高频分量,该分量可作为汽轮机断叶片故障的征兆.
Through the harmonic vibration testing of single-stage bladed disc, it shows that the high frequency componenet related to blade number in frequency spectrum is very obvious when a blade breaks, which may be taken as a symptom of blade broken failure. Figs 3 and tables 2.
