| Abstract: | In this paper, a natural frequency-measuring device for turbine blade is developed, and its constructing and working principles based on spectrum analysis are presented. The built-in electric charge transformer, program-controlled filters and signals amplifier made the device with compact structure and smaller bulk. The use of all Chinese characters' working interfaces made it easy to operating. The field experimental results indicate the device has higher measurement accuracy and reliability, thus updating the natural frequency measurement method of turbine blades. |
