| Abstract: | Finite element models for calculating dynamic characteristics of a power turbine hollow shaft assembly and rotors (with hollow or solid transmission shaft) of a new-type turbo-shaft engine are set up by SAMCEF/ROTOR software. Based on obtained numerical results of critical speeds, vibration modes and responses due to unbalance, influence of the transmission shaft, the torque tube and the power turbine disks on dynamic characteristics of the rotor are analyzed. It is shown that the influence of power turbine disks on dynamic characteristics is much greater than that of transmission shaft or torque tube, and critical speeds design of power turbine rotor used in engine is reasonable. This research provides theoretical basis for improving design or reference for designing and calculating dynamic characteristics of similar rotors. |
