| 摘 要： | 为研究机组在瞬态载荷作用下的运动规律，建立了大型水轮发电机组瞬态动力响应模型。模型将机组整个轴系的主轴、发电机转子、水轮机转轮及各轴承支承条件耦合起来，考虑了机组轴系的连续质量、转动惯量及摆动惯性。采取有限单元法和直接数值积分法相结合的方法，结合工程实例，对机组在瞬时初位移和瞬时不平衡载荷作用下的时程响应及轴心轨迹分别进行了计算机仿真计算，并对计算结果进行了分析和讨论。此计算模型、计算方法及总结的规律为大型水轮发电机组的振动研究提供了有益的参考。

| Abstract: | In order to study the unit's movement law,a transient dynamic response model of large hydroelectric machines is established.The model couples the whole unit such as main shaft,generator rotor,turbine runner and various bearing supporting,and involves consistent quality of the unit shaft,gyroscopic inertia and angular inertia.The finite element method and direct numerical integration method are used in the calculation.Through an engineering example,the numerical simulations of time-course response and axes c... |
