| 摘 要： | 以某兆瓦级风电机组为例，根据德国劳埃德2010版风机认证规范要求，绘制了机组传动链动力学拓扑图，建立了包含多自由度刚柔部件的机组传动链模型。根据传动链模型，进行了频域分析，得到了机组传动链模态频率，绘制了二维Campbell图，找到了传动链潜在共振点，并通过时域扫频分析，验证了共振点的分析结果。与Bladed结果进行比较，验证了仿真分析结果的正确性。

| Abstract: | A topology graph of the drive train for mega-watts wind turbine has been drawn and a multi-body dynamic model of the drive train has been built according to GL2010 guideline. Firstly, frequency-domain analysis has been conducted based on the model, the modal frequency of the drive train has been found, and 2D Campbell diagram has been generated to find the potential point of reso?nance. Secondly, the analysis result of resonance point has been verified by sweep analysis in time-domain. The correctness of the sim?ulation result has been verified by comparing with the Bladed result. |
