METHOD AND SYSTEM FOR MEASURING VIBRATION GENERATED IN ON-LINE TURBINE BLADES

摘要

PURPOSE: A method and a system for measuring vibration of a turbine blade in operation are provided to efficiently prevent damage to a turbine blade caused by vibration and enable easy and accurate measurement of vibration. CONSTITUTION: A system for measuring vibration of a turbine blade in operation comprises a vibration sensor(310), a wireless transmission device(320), and an energy collecting device(330). The vibration sensor, which senses the vibration of a turbine blade being rotated, obtains a vibration signal at the optimal approach distance to the turbine blade. The wireless transmission device receives in real time the vibration information of the vibration signal obtained by the vibration sensor and transmits the vibration information to a vibration analyzer located outside the turbine blade. The energy collecting device collects the vibration energy generated by the rotation of the turbine blade.
