| Abstract: |
| The calculating method of nonlinear dynamic response of rotor-bearing system of hydroelectric machines is discussed.On the basis of building the nonlinear dynamic model of the rotor-bearing system,the calculating formula of dynamics response of the system is given by using the Wilson-θ method and the Riccati transfer matrix method.The validated experiment indicates that the computational procedure is simple and trusty.It is able to meet the need of calculating the dynamic responses of the system in engineering. |
