摘要
用阻尼涂层对整体叶盘进行减振是一种全新的振动控制方法,为了有效实施这项技术需要对不同涂层方案下整体叶盘振动局部化程度进行有效的测量.提出一种基于试验模态数据来定量化测量整体叶盘振动局部化的方法.首先,提出振动局部化定量测量原理,并验证了其合理性;接着,提出了测量涂层整体叶盘振动局部化的流程;最后,对3种涂层方案下整体叶盘振动局部化程度进行了测量.结果表明,用本文研发的方法可以对各涂层方案对应的整体叶盘振动局部化进行有效测量,且随着涂层面积的增加,整体叶盘振动局部化程度变大且波动也较大.
Vibration control of blisk by attaching damping coating is a newtechnique. To implement this technology effectively,it is necessary to measure the degree of vibration localization of blisk for different coating schemes. Based on experimental modal data, a quantitative measurement method for the vibration localization of blisk is proposed. Firstly,the theory of quantitative measurement of the degree of vibration localization was proposed,and the reasonability was verified. Then,the procedure of quantitative measurement of vibration localization of blisk with damping coating was presented. Lastly,the vibration localizations of blisk with three coating schemes were tested. The results showed that the developed method can effectively measure the vibration localization of blisk with different coating schemes and the degree of vibration localization of blisk becomes more evident and fluctuates with the increase of coating area.
