A coupled fluid-mechanical dynamics analysis method is presented in this paper. A commercial simulation package is used for mechanical dynamics calculation, which employs user-developed dynamic-link library files as routine interface to enable data exchange with gas pressure calculation. This part is responsible for the calculation of mechanical motion, including the tripping of trip trigger, releasing...
Owing to their high efficiency and power density, high-speed permanent magnet (PM) brushless machines are emerging as a key technology for applications as varied as spindle drives, centrifugal compressors, turbo-molecular pumps, gas-turbine generator units, and electric/hybrid vehicle traction systems [1].
In order to improve the flatness of hot rolled strip in hot strip finishing mills, a novel segmented looper system is developed, which called the Flatness Sensing Inter-stand Looper (FlatSIL) system. The FlatSIL system measures the tension along the direction of the strip width by using segmented rolls, and the tension profile is calculated. Using the tension profile, the flatness control system of...
The feasibility of designing a multistage depressed collector using conformal finite-difference time-domain particle-in-cell simulations has been studied. A feedback mechanism is implemented to provide stable time-dependent voltages for each stage of the depressed collector. An arbitrary space-time dependent spent beam distribution can be given in our time-domain simulations. We demonstrate the design...
We report a simulation program for indoor visible light communication environment based on MATLAB and Simulink. The program considers the positions of the transmitters and the reflections at each wall. For visible light communication environment, the illumination light-emitting diode is used not only as a lighting device, but also as a communication device. Using the simulation program, the distributions...
