摘　　要：以某型减摇陀螺装置飞轮为研究对象,采用ANSYS Workbench建立有限元模型,对飞轮进行模态分析,计算飞轮自身的临界转速并绘制坎贝尔图;结合飞轮本身的不平衡量,通过谐响应分析方法得到飞轮的稳态不平衡响应曲线。结果显示:飞轮的1阶临界转速为8732.5 r/min,工作转速低于1阶临界转速的70%,不会产生共振;在不平衡量的作用下,飞轮在202 Hz、218 Hz下会产生明显的共振现象,该频率远高于飞轮的工作转速,因此在飞轮正常工作时不会受到飞轮不平衡量引起的共振。证明该型减摇陀螺装置飞轮设计的合理性,同时对后续同类型飞轮的设计提供仿真参考。Taking the flywheel of a type of ship gyro-stabilizer as the research object,establish finite element model with ANSYS Workbench to launch the modal analysis of the flywheel,and calculate the critical speed of the flywheel and the Campbell diagram is drawn.Then combined with the unbalance of the flywheel itself,the steady-state unbalance response curve of the flywheel is obtained by harmonic response analysis method.The results show that the first critical speed of the flywheel is 8732.5 r/min,and the working speed is lower than 70%of the first critical speed,so there is no resonance.Under the action of the unbalance,the flywheel will have obvious resonance at 202 Hz and 218 Hz.This frequency is far higher than the working speed of the flywheel,so the flywheel will not be subject to the resonance caused by the flywheel unbalance during normal operation.The rationality of the flywheel design of this type of anti rolling gyro device is proved,and the simulation reference for the subsequent design of the same type of flywheel is provided.
