[0002] The web of a wind turbine blade generally adopts a frame structure, and the wind load and inertia load of the blade must be considered during the design and manufacturing process. At the same time, when designing the web structure, factors such as the blade geometry, length and tip load must also be considered. The wind turbine blade is mainly made of PS face shell, SS face shell and web, which are molded and bonded using mold glue. As a structural component connecting the two shells, the web plays an important role in the strength of the wind turbine blade. The wind turbine blade web is one of the most critical components in the entire blade system, responsible for supporting the blade and transmitting the aerodynamic load.
