Dynamic performance analysis of the X4 high-speed pick-and-place parallel robot

In order to meet high-speed machining center’s overall performance requirements, there are four different worktable structures established in SolidWorks, and they are carried out static analysis in ANSYS Workbench to calculate their static stiffness, so that find out the best structure. In meeting the worktable stiffness, the best structure is optimized in ANSYS Workbench, then the worktable’s quality reduces 8.43% in the original foundation and the cost also decreases, which is a basis for worktable’s dynamic performance analysis.

Pick And Place Operation

The dynamic modeling and analysis of a 2-DOF translational parallel robot for high-speed pick-and-place operation was presented. Considering the flexibility of all links, the governing equation of motion of a flexible link is formulated in the floating frame of reference using Euler-Lagrange method. A kineto-elasto dynamic model of the system is achieved, ready for modal analysis. Simulation in FEM software showed the similar modes with above computational result in typical location and rotation. The dynamic experiment presented the dominant modes and proved the theoretical analysis and simulation. The Diamond robot used in Lithium-ion battery sorting was taken as an example to demonstrate how to finish above studies. The result shows that the mechanism has good dynamic performance. The work is available for all parallel robots with flexible links.

A Company

The beam of embroidery machine vibrates more intensely and breakage rate goes higher when the spindle rotates at 850rpm and then the quality of product reduces drastically. One high-speed computerized embroidery machine with 20 heads manufactured by a company in Jiangmen was studied for the problem mentioned above. Dynamic performance analysis was conducted to the beam by analytical experiment and computation based on FEM through ANSYS. One improvement solution was proposed and theoretical verification to the optimized beam was processed. It provides a reference for the improvement on embroiderys structure and the development of new model in the future.

High Speed Switching

Based on the rheological mechanism of magnetorheological fluid，we can design a kind of magnetorheological high-speed on-off valves,which used the Plug-in structure.It is shows that， through the static and dynamic performance analysis of the valves，the magnetorheological high-speed on-off valves not only has the good static, dynamic characteristics, compare to magnetorheological plug-mounted speed switch valve with traditional hydraulic, and with high speed of response, high stability, etc . It is an easy to achieve automatic control and intelligent control of the hydraulic components.
