摘要：

In order to explore the influence of clearance and flexibility on the torsional vibration of the compressor rotor system, a torsional vibration calculation model of the compressor crankshaft system that takes into account the influence of contact clearance and flexibility characteristics is proposed. The simulation results show that frictional impacts occur between the second and fourth rows of the crankshaft bushings and the pin. In addition, the transmission torque of the coupling is lost by 7.1%. Meanwhile, compressor vibration test experiments were carried out, and the vibration speed error of the free end of the crankshaft system under experiment and simulation was 11.9%, which verified the accuracy of the research method and model. On this basis, the dynamic response of torsional vibration of the crankshaft system under different clearances and different driving speeds was further investigated. The results show that the larger the clearance and speed, the worse the matching of power transmission of the crankshaft system, but the standard deviation of piston acceleration shows a high-lowhigh trend with the increase of rotational speed, indicating that there is room for adjustment of rotational speed. The study has certain guiding significance for improving the operation stability of the compressor.
