Static Analysis and Modal Analysis of Heavy-Load Manipulator Based on ANSYS

The heavy-load manipulator arm, an important part of the remote handling maintenance system of the large-scale multi-purpose deployer, plays a key role of the entire system. Its modeling and assembly was finished by Pro/E. Then use the ANSYS Workbench, finite element analysis software, to complete its static analysis and modal analysis through building a seamless connection between Pro/E and ANSYS Workbench. As a result, the overall deformation and static stiffness values of the manipulator arm were obtained through static analysis, and the former six-order natural frequency values and mode shapes were obtained through modal analysis. Finally, scheme of structure modification and new control method were presented by analyzing and comparing the results.
