AI Technical Summary
The existing fixing devices used for wind turbine nacelle testing cannot simulate the boundary conditions of actual bolted connections or flange seals, resulting in distorted mechanical boundary conditions and insufficient environmental adaptability. This fails to meet the stringent testing requirements of the wind power industry and leads to inaccurate test data.
The test connection seat, positioning platform and counterweight are combined to accurately simulate the actual installation point and load transmission path of the canopy, so as to achieve accurate simulation of boundary conditions. The design of the positioning frame module, support base module and suspension frame ensures that the installation point is consistent with the bolt position inside the canopy and the vibration load is transmitted without distortion.
It ensures the authenticity and reliability of wind turbine nacelle test data, improves the accuracy and reliability of testing, can reproduce multi-condition compatible test conditions, and improves disassembly and assembly efficiency and safety.
