非接触式转子叶片振动测试技术应用研究

Investigation and application of non-contact rotor blade vibration measurement technique

介绍了旋转叶片整数阶次与非整数阶次的振动理论分析,并利用非接触式叶片振动测量系统进行了模拟试验器和台架压气机试验验证.理论分析和试验结果吻合,表明由非接触式叶片振动测量系统测试振幅的变化特征,可确定整阶次共振与非整阶次叶片振动.

This paper briefly describes non-contact rotor blade vibration measurement analysis methods. Theoretical analysis was conducted for both asynchronous and synchronous resonant vibrations. This system has been applied successfully in compressor and engine testing and the theoretical predictions were validated by results from strain gauge measurement.
