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.

This article designed a kind of magnetorheological high-speed on-off valves and made optimized design based on the nature of the magnetorheological fluid(MRF). ANSYS software was used to analyze magnetic field of the two different structures and get the magnetic flux lines distribution and flux density map. The simulation analysis results show that: optimized high speed switching valve, can reduce the loss of the coil and the rise of temperature, improves the life of the valve body, it also can shorten the switching response time and improves the reliability of the valve.

High Speed Switching

The switched inertance hydraulic system (SIHS) is a novel high-bandwidth and energy-efficient digital device which can adjust or control flow and pressure by a means that does not rely on throttling the flow and dissipation of power. An SIHS can provide an efficient step-up or step-down of pressure or flow rate by using a digital control signal. In this article, analytical models of an SIHS in a four-port high-speed switching valve configuration are proposed, and the system dynamics and performance are investigated theoretically and experimentally. The flow responses, system characteristics and power consumption can be predicted effectively and accurately by using the proposed models, which were validated by comparing with experiments and with numerical simulation. The four-port configuration is compared with the three-port configuration, and it is concluded that the former one is less efficient for valves of the same size, but provides a bi-direction control capability. As bi-direction control is a common requirement, this constitutes an important contribution to the development of efficient digital hydraulics.
