摘要
应用非接触式数字光纤叶片测振系统对叶片整数阶次振动(共振)与非整数阶次振动进行了分析。通过模拟试验器和台架压气机试验证明,应用该系统以及相关算法可以有效测量、监测和分析叶片共振和颤振等非整阶次振动,能较准确地评估叶片振动特征;其结果与应变片测量结果一致。
The analysis of integer order and non-integer order vibrations for rotor blade were performed by non-contact digital optic fiber rotor blade vibration measurement system. The simulated and compressor rig test results indicate that the non-integer order vibration such as blade resonance and flutter are effectively measured, monitored and analyzed using this system and the related algorithmand the blade vibration characteristics are accurately estimated. The result is consistent with the measurement of the strain gauge.
