摘要
举例说明了在动力转子系统中陀螺效应对实际模型的影响。着重分析了转子陀螺效应对进动角速度、振型以及临界角速度的影响。并应用状态空间法求解陀螺系统的本征值问题。数值结果表明,在一些工程问题中,陀螺力对于转子系统振动特性的影响是不能忽略的。
In some engineering problems, some computing models ignore gyroscopic moment. However, the effects of gyroscopic upon the true model can not be ignored. The effects of gyroscopic upon the processional frequency, mode and critical speed for a rotor system are demonstrated by an example in this paper. The state space method is used to solve the eigenvalue problem. Numerical results show that the gyroscopic effect can not be ignored in some vibration analysis problems.
