In order to improve the harvesting efficiency of forest-fruit, the structure characteristics of the Harvesting Ro-bot Arm was introduced , the harvesting robot should have more reasonable structure and dynamic performance .Based on the modal analysis theory , a finite element model of the harvesting robot arm was established by utilizing the software of ANSYS Workbench .Three kinds of typical pose were selected , further more , the preceding six steps natural frequency and mode were obtained .Last but not at least , the weak parts of the robot arm were found out and relative improving su ggest...
