Based on the Riccati transfer matrix method and the Wilson-θ integral method, an effective method to calculate the transient response of a rotor-bearing system is presented in this paper. The flexible rotor with a sliding bearing can be excited by any force f (t) or basic motion. The chock and foundation are simplified as mass, damper and spring model.The method provided in this paper has the merits of numerical stability and simple procedure.A few examples show that this numerical solution is very effective.
