Abstract

Dynamic characteristics of the hydraulic arm affects the mobile coal sampling robot’s accuracy and efficiency. The complex and varied working conditions put many high requirements on the stability of the hydraulic arm. This paper took the hydraulic arm of the MCYY2000 mobile coal sampling robot as the research object, and established a simplified model of the hydraulic arm with SolidWorks. It carried out the analysis under both the condition of no-sampling resistance and the condition of variable sampling resistance. The analysis was done with the module of multi-body dynamics simulation in Simulink. This paper helps to obtain the joint torques and hydraulic driving forces of the hydraulic arm under different conditions. The results provide a basis for further work including accurate motion control, chatter reduction and safety improvement of the coal sampling robot.
