针对风电叶片单点疲劳加载方法驱动能力不足且试验周期较长的问题，设计一种新型两点疲劳加载测试系统。通过对加载系统进行合理简化，建立风电叶片两点疲劳加载振动系统的机电耦合数学模型。利用Matlab/Simulink软件建立加载系统的仿真模型，对加载系统的机电耦合过程进行仿真，得到不同电动机转速、不同初始相位差对加载系统机电耦合过程的基本影响规律。最后搭建了一套小型风电叶片两点疲劳加载试验系统，得到试验结果与仿真结果规律基本吻合，验证了数学模型和仿真模型的准确性。为后续两点疲劳加载试验的精确控制以及叶片的优化设计提供了理论依据。
Abstract
To solve the problem of small driven capacity and long test period of single-point fatigue loading system, a dual-point fatigue loading system of wind turbine blade is designed. By simplifying the loading system rationally, its electromechanical coupling mathematical model is established, and then its simulation model is built with Matlab/Simulink software. By simulating the electromechanical coupling process of the dual-point fatigue vibration system, the basic influence laws of different motor speed and different initial phase are obtained. Finally, a small dual-point fatigue loading test system of wind turbine blade is set up and the test results are consistent with the simulation results. The accuracy of the mathematical model and simulation model is validated, which provides a theoretical basis for the subsequent precise control of dual-point fatigue loading test and optimal design of the blade.
