摘要:

The main shaft serves as a critical component in the wind turbine transmission system, and carries the torque transmitted by the turbine hub. However, the surface of the main shaft is vulnerable to fatigue cracks under the external harsh environmental factors. And the cracks are a serious threat to the safe operation of the turbine. To detect these defects, an electromagnetic acoustic transducer designed to fit the central hole of the spindle was introduced. Based on the Lorentz force effect and the magnetostriction, the finite element simulation model of the EMAT transducer was established, to analyze the acoustic beam deflection angle and acoustic field intensity change range. Also, the details analyze the law of influencing factors on transducer efficiency, such as magnet size, number, layer number, coil splitting and so on. The optimized transducer detects effectively surface defects on the spindle sample in the crack detection experiments. Moreover, the sector scanning detection of surface cracks can be demonstrate by adjusting the frequency, and the defect positioning error is less than 3 mm. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
