In view of the national development requirements and the current situation of China in the field of CNC machine tools, its related characteristics are deeply explored. The nonlinear dynamic model of the system is constructed and basic assumptions are made. Through numerical simulation, the influence of different parameters on the vibration characteristics of the system is analyzed, including rotational speed, eccentricity, bearing clearance, etc. The bifurcation characteristics of the benchmark model and the change in the motion state of the system under different bearing clearances and eccentricities are comprehensively studied. The research results provide a theoretical basis for the design and operation of this system, which is helpful in improving the safety, high efficiency, and stability of the system and is of great significance for improving the quality of CNC machine tools.
