摘要
根据某1000MW机组进行有限元建模;然后计算轴系临界转速,与实测值比较,验证模型的合理性;再研究励磁机一阶临界接近于工作转速的三支撑结构响应特性,并结合工程案例分析,进一步验证结论的可靠性。
Finite element model based on a IO00MW unit is set up. And then critical speed is calculated that compared to actual measured value to verify the rationality of the model. Lastly response characteristics of the three-bearings supporting structure are studied when the first critical speed of the exciter is closed to the working speed. And the reliability of conclusions is further verified by case analysis.
