【Abstract】 The finite element model of U-shaped truss manipulator is established using SolidWorks, and the most reasonable three-dimensional model is obtained according to the principle of model simplification. Stress cloud maps, deformation cloud maps and the first six natural frequencies and modes can be calculated by static analysis and modal analysis, with the help of engineering analysis software ANSYS Workbench 15.0. The analysis can prove the rationality of the U-shaped truss. And the use of lightweight design to optimize the truss structure for the future truss robot design has a certain reference value.更多还原
