The spindle hydraulic system of the rolling riveting machine was used as the research object,the hydraulic system model was established by MATLAB/Simulink,and the stability analysis was carried out.The analysis results showed the hydraulic system was unstable and its correction analysis was carried out.Once again the simulation,the corrected rolling riveting machine spindle hydraulic system was stable.The results show that:the efficiency of the hydraulic system is high by Simulink,which provides theoretical basis for the research and development of the following rolling riveting machine.
