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.

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.

Finger seal is an advanced compliant seal and can be utilized to separate high (HP) and low pressure (LP) zones in high speed rotating shaft environment. The work to be presented concerns the dynamic behavior of a repetitive section of a two-layer finger seal with high-and padded low-pressure laminates. The dynamic performance of the finger seal are analyzed by the coupled fluid-solid-interaction (FSI) simulations. By using the commercial software ANSYS-CFX, the numerical simulation results of interactions between the gas flow and fingers structural deformation are described when the radial periodic excitation from the shaft applies to the finger seal. And the gas film loading capacity, gas film stiffness and leakage varied with time are put forward in different working conditions. Compared with the dynamic performance analysis results based on equivalent dynamic method, the FSI dynamic analysis shows some different characteristics which are more accordance with actual circumstance. Moreover, it is shown that under low pressure differential and high rotation speed the non-contacting finger seal with advance features both in sealing effectiveness and potential unlimited life span can be obtained by rational structure design. But for the non-contacting finger seal with circumferential convergent pad working in high pressure and low rotating speed conditions, it is difficult to improve the sealing performance by the way of changing the structure parameters of finger seal. It is because the high pressure plays a major role on this sealing situation.

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.
