Abstract: To analyze the influence of rotor parameters on the response characteristics of the startup process, a simplified single-disk cantilever rotor model of a torpedo turbine rotor system is established, and its transient differential equation is derived by using the Riccati transfer matrix method. Moreover, the Newmark-β method is used to solve the startup process response of the rotor. The influence of the law of angular acceleration, damping coefficient, and other parameters on the response of the rotor during the startup process is analyzed. The results show that an increase in the angular acceleration leads to a decrease in the resonance amplitude and a slight increase in the resonance speed. Furthermore, an increase in the damping coefficient results in a decrease in the resonance amplitude and a slight decrease in the resonance speed. The results can be used as a reference and have theoretical significance for the research on transient dynamic balance and rational design of elastic ring structures of a rotor.
