精铣叶根的叶片测频问题分析与对策

Analysis and Countermeasure of Blade Frequency Measurement in Finish-milling Blade Root

文章主要针对精铣加工叶根后,对引起测频叶片的频率值偏低的原因进行了分析。为验证分析结论的正确性,进行了相关验证试验,最终指出影响精铣叶根的叶片频率值偏低的主要因素,并针对这些主要影响因素,提出相应解决对策。

In the paper, lhe reasons were analyzed which the measure frequency was lower than the standard relevant validation experiments. In order to verify the correctness of the analysis conchesion, the relevant verification test was carried out. Finally, the key factors that affected tire low frequency value of the finish-milling blade were pointed out, and tire corresponding contermeasnre were put forward according to the main influencing factors.
