چکیده
Currently, the existing study on rotor system with disk-shaft clearance primarily focuses on analyzing factors such as interference force and friction coefficient while neglecting the vibration characteristics during the rotational states. Therefore, a finite element model is established by taking rotor systems with disk-shaft clearance as the research object. The vibration characteristics of rotor systems under different clearances or rotation speeds are analyzed. Increasing clearance leads to gradual fluctuations in the speed difference of shaft to disk, accompanied by an increasing periodicity of these fluctuations. In the time domain diagram, beat vibration characteristic become evident, and its period undergoes noticeable changes. The amplitude of rotation frequency increases, while that of multiple frequency decreases gradually and tends to a constant value. The presence of clearance causes the orbit of the disk center to become an irregular circle, and the shape of 8 appears. Additionally, collision and friction of shaft to disk result in apparent serrations in the orbit. As the rotational speed increases, the speed difference initially increases but eventually reaches a stable value. The beat vibration characteristic disappears due to the small speed difference, leading to a small amplitude of the multiple frequency. The orbit of the disk center tends to become circular, and the serrated phenomenon weakens and disappears. Finally, the experiments of rotor systems with disk-shaft clearance are carried out. The results are in good agreement with the simulations, which verifies the correctness of the dynamic model. The research results can provide a theoretical basis for understanding rotor systems with disk-shaft clearance.
