摘要
采用叶素动量理论进行风力机气动力学的计算分析,并对风轮和塔架进行了有限元模态分析,建立风力机ADAMS柔性多体动力学仿真模型,并在MATLAB/Simulink环境下建立风力机传动链的数学模型,同时进行传动链系统的编程运算,充分考虑了气弹耦合特性以及传动系统的影响,最终实现在MATLAB/Simulink和ADAMS基础上对风力机系统振动性能的联合仿真。仿真数据同国际有名的风力机分析软件Bladed计算数据比较表明,该联合仿真方法可以较好地模拟风力机的振动特性。
The aerodynamic characteristic of wind turbine is calculated by applying the Blade Element Momentum (BEM) theory. Also finite element mode analysis is clone for the tower and the rotor. Then the multi-dynamic model of the wind turbine is built in Adams. Also the drive chain is calculated by applying state space method and programmed in Matlab/Simulink. With that the combined simulation of vibration characteristics is carried out on the base of MATLAB/ Simulink and ADAMS, in which the transmission effects and aero-elasticity coupling is fully considered. The results show that the method is able to simulate the vibration characteristic almost the same as software Bladed, which is wellknown for analyzing performance and loads for the design and certification of wind turbines.
