摘要：From basic dynamical characteristics and energy composition of shafting, the differential equation model of shafting vibration is built, in which various additional forces acted on the shafting of hydro turbine generating sets are taken as additional input controls. And then differential equation model is transformed into the generalized Hamiltonian control model of hydro turbine generating sets shafting. In this model, additional forces acted on shafting are taken as input inspire of system, and be used to research their effects on shafting motion. Further, the additional forces can be merged into the system matrix of Hamiltonian model, and then physical conceptions of the structure and damping matrix of Hamiltonian system can be employed to research the coupling dynamics mechanism between shafting and additional forces. Proposed model is form concise and good commonality.
