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.

DVG850 high-speed machining center worktable is taken as research object, in order to meet the overall performance requirements of the high-speed machining center, 3D model of worktable is established in SolidWorks. Static analysis and modal analysis are carried out in ANSYS Workbench, and then the worktable is optimized in topology optimization module of ANSYS Workbench. According with the analysis results, the worktable structure has improved. The improved worktable keeps the original’s static performance, and enhances the dynamic performance; however, its quality is lighter than original structure by 23.2 kg.

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.

The main work is calculating and analyzing the worktable’s static stiffness in different positions, and drawing 3D static stiffness spectrum of the worktable in Z direction according to the analyzing results. DVG850 High-speed machining centre is taken as the research object, to establish the solid modal in ANSYS Workbench and analyze the worktable’s static stiffness in different positions. and the paper uses its worktable as the researching object. According to the results the spectrum of the static stiffness of the worktable is drawing in Matlab. The spectrum shows that the more the position is near the edge, the larger the static stiffness is, and it changes faster, however the middle is smaller. This spectrum has certain directive significance for the optimal design and improvement of product quality of design.

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.
