In view of the existing impact equipment can't meet the needs of continuous high speed impact experiment, a new type of high speed multiple impact experiment method is proposed and the principle of system design is also given. The experiment system is mainly composed of impact system, automatic feed system and the control system, Wherein the main components of the impact system is a horizontal turntable...
Metasurfaces in metal/insulator/metal configuration have been widely used in photonics, with applications ranging from perfect absorption to phase modulation, but why and when such structures can realize what functionalities are not yet fully understood. Here, we establish a complete phase diagram in which the optical properties of such systems are fully controlled by two simple parameters (i.e.,...
Metal/insulator/metal metasurfaces have widely applications ranging from perfect absorption to phase modulation, but the mechanism of these functionalities are not yet fully understood. Here, based on a coupled-mode analysis, we establish a complete phase diagram through two simple parameters, which lays a solid basis for realizing functional and tunable photonic devices with such structures.
Metasurfaces in metal/insulator/metal configuration have recently been widely used in photonics research, with applications ranging from perfect absorption to phase modulation [1, 2], but why and when such structures can realize what kinds of functionalities are not fully understood. Here, based on coupled-model analysis, we establish a complete phase diagram for such systems, in which their optical...
The internal turbine mechanism is a new sensor that can be used for independent velocity measurement of underwater high speed moving body. It is a meaningful study when the cavitation flow field around and trajectory changes of the high speed moving body was taken into consideration. The parameterization of turbine mechanism was done at first. Then the surrounding flow field was analyzed and the CFD...
Accurate static electromagnetic characteristics are essential basic data in the modeling of switched reluctance machine (SRM) for performance analysis and advanced control purposes. Because of the doubly salient structure and deep magnetic saturation, the electromagnetic characteristics of SRM have highly nonlinear relations with phase current and rotor position, which make the determination of these...
In this paper, a computer-based system is presented to measure the static electromagnetic characteristics (SECs) of switched reluctance machines (SRM), including magnetization characteristics (MCs) and torque characteristics (TCs). The MCs are measured indirectly based on phase voltage and current by digital integration technology with rotor mechanically locked, while the TCs are directly determined...
For the real-time information communication of fuze and fire control system, a wire link setting technology is adopted to realize the dual-direction quick transmission of information between setting system and fuze circuit. In order to reduce energy consumption of the fuze circuit during the information feedback process, a setting system loop is designed based on the load modulation technology with...
