The key to the research on the dynamic characteristics of hydro-generating units is to establish the correct mathematical model, to determine the boundary conditions of important components and to adopt a stable and high-precision solving method. This paper discusses the solution of the dynamic response of the main shaft system and the modeling method. The boundary conditions of several important related components are analyzed, that is, the dynamic modeling of the bearing components
