摘要：
Here, taking power turbine rotor of a certain shipborne turboprop engine as the study object, a simulated rotor with the same dynamic characteristics as the actual rotor was designed based on the principle of dynamic similarity design, and the correctness of the dynamic similarity design was verified. A test method for rotor vibration characteristics under impact load was proposed, and anti-impact performance of high-speed motor and vibration characteristics of rotors under impact load were studied on a shaking table. It was verified that high-speed motors have vertical anti-impact performance of no less than I0g. Transient vibration responses of rotors under impact load were extracted, and their main frequency components during impact were obtained. The study showed that dynamic characteristics of a simulated rotor have good consistency to those of the actual rotor; a rotor' s fundamental frequency in its vibration responses remains unchanged during impact, but more complex other frequency components exist in vibration responses; the study results provide a technical support for development of a certain shipborne turboprop engine and a method for dynamic tests of rotor under impact load. © 2023 Chinese Vibration Engineering Society.
