To investigate the influence of loading opportunity of shock excitations on dynamic responses of rotor-bearing systems subjected to base shock excitations, dynamic differential equations of a rigid rotor-bearing system were established. Gyroscopic effect and mass eccentricity of the rotor were considered. Shock responses were obtained by numerical simulation. Four cases are investigated that will...
The conventional Newmark method based on average acceleration concept cannot be directly applied to solve state-space first-order differential equations, which contains no explicit acceleration terms. Combining with a Newmark iteration algorithm based on average velocity concept, a Riccati-transfer matrix method was proposed to obtain transient response of rotor systems under base shock excitations...
