[0002] As the global demand for clean energy continues to grow, wind power generation, as a renewable and pollution-free way of obtaining energy, has been widely used and developed rapidly. The blades of wind turbines are one of the key components in the wind power generation system. Their performance and quality directly affect the efficiency and stability of the entire wind power generation system. In the production process of wind turbine blades, it is crucial to ensure that the quality and performance of the blades meet strict standards. However, the existing detection technologies and methods have many shortcomings. Traditional detection methods often rely on manual visual inspection and simple measuring tools. This method is not only inefficient, but also difficult to ensure the accuracy and reliability of the detection results. In the production process of wind turbine blades, it is crucial to ensure that the blades have sufficient strength to withstand complex wind conditions and long-term operation fatigue stress. However, the existing detection methods and technologies have many shortcomings.
[0003] Traditional strength detection methods such as ultrasonic detection and X-ray detection, although they can perform detection without destroying the blades, have problems such as limited detection accuracy, complex operation, and low detection efficiency. Due to the complex shape and structure of wind turbine blades, existing detection technologies often have detection blind spots when detecting different parts of the blades, and cannot fully and accurately evaluate the strength of the blades. At the same time, since wind turbine blades are often in a dynamic working environment, the compressive strength of wind turbine blades detected under static conditions is not completely consistent with the compressive strength under actual working conditions, which also causes inaccurate test results.
