Abstract：In order to meet the requirements of high reliability and positioning accuracy for pole changing robotic arms in the working environment of mines,it is necessary to analyze their structural dynamic and static characteristics.The rod changing robotic arm were took as the research object,its finite element model was established,and static analysis,modal analysis,and harmonic response analysis were conducted when using software.The static analysis results indicated that under the maximum load,the positioning accuracy and structural strength of the robotic arm met the design requirements.The modal analysis results indicated that the first six natural frequencies and vibration modes of the robotic arm were suitable for the working environment and would not produce resonance phenomena.The harmonic response analysis results indicated that the dynamic load response of the robotic arm was mainly influenced by the second and fourth order natural frequencies.The analysis data provided a reference basis for the dynamic design of the underground pole changing robotic arm.
