This paper analyzes the electromechanics of the spherical metal particles in AC gasinsulated lines (GIL) with a pragmatic test rig comprising coaxial cylindrical electrodes. Analysis on fluid resistance during the particle moving process is presented based on fluid mechanics as well as the kinetic parameters of the SF6/N2 mixture. The interactive impacts between the particle and the conductor or the...
The aerodynamic characteristics directly affect driving characteristics, stability, operation, oil consumption, and safety of automobiles. The virtual wind tunnel experiment simulation based on finite element method has provided useful theoretical reference to automobile bodywork design. In this study, the air flow and distribution information around the automobiles was obtained using aerodynamic...
As the thrust of wastewater treatment mixer is a blank in current research in domestic, hydrodynamic analysis on the blade of the wastewater treatment mixer was used in this paper based on lifting theory of fluid mechanics, and the calculation formula of hydraulic thrust was deduced and demonstrated, which is significant in theory and valuable in practice. After analysis, the hydraulic thrust of wastewater...
Force information in virtual space is important and often required for tele-operation, training, amusement, design supporting, and other virtual reality systems. The application of passive-type force display and rehabilitation system is desirable for its high safety. However, there are some directions and link positions for which it is difficult to display the force using only passive elements. To...
We developed a compact and low-cost quasi-3-DOF rehabilitation system ldquoHybrid-PLEMOrdquo for upper limbs of stroke patients. Hybrid-PLEMO has 2-DOF force feedback function in working plane, its working plane can be adjusted the inclination, and it can be switched between active type and passive type. However, there are some directions and link positions which are difficult to display the force...
Several 2-DOF rehabilitation robots for upper limbs have been proposed so far, and clinical effectiveness was reported in several studies for the aged people or patients with stroke. We developed the quasi 3-DOF rehabilitation system ldquoHybrid PLEMOrdquo which has 2-DOF force-feedback function in working plane but its working plane can be adjusted the inclination. Hybrid-PLEMO is a compact, low-cost...
This paper presents a new structure of a Magneto Rheological (MR) brake which generates the resistance force based on the effect of material deformation process. A rotary disk is proposed and fabricated with the wave form boundary. Thus, the chains of an MR fluid are crushed together instead of being strained to break as known in the conventional design. The phenomenon of mechanical destruction creates...
