Multi-degree of freedom manipulators have become a hotspot in the field of robotics because of many advantages. In this paper, a 5-DOF manipulator was taken as the object of study. The modal analysis on it was carried out by methods of test and finite element analysis. A model updating method based on sensitivity analysis was put forward, and the final finite element model was established by iterative...
The dynamic response analysis to simulate the complicated working condition can ensure the high reliability of space products' design. In this paper, we focus on the solar array of a satellite, and gain equivalent mechanical parameters of its internal honeycomb panel's construction. We build an accurate finite element model, and perform modal analysis and frequency response analysis as well. By contrast,...
The article focuses on the friction stir welding (FSW) robot and introduces the system structure of it as well as five kinds of typical welding conditions. Through establishing the six dimensional stiffness model of guide screw's joint and presenting a numerical simulation method of flexible joint, this paper improves the accuracy of the engine's finite element model, and then analysis the effect...
