 When an alternating electric current flows through a conductor (wire), Electric-E and Magnetic-H fields are created around the conductor.  If the length of the conductor is very short compared to a wavelength (<< λ/4), the electric and magnetic fields will decrease dramatically within a distance of one or two wavelengths.  However, as the conductor is lengthened, the intensity of the fields...

The inception voltage of the positive corona discharges (CIV) in a typical wire-cylinder electrode arrangement in air, under high voltage dc application, has been studied by implementing the Finite Element Analysis (FEA). Numerical analysis has been carried out on the electric field intensity, along the wire-cylinder gap axis, in order to determine the inception voltage of each air gap and defi...

Terahertz pulses trapped as surface waves on a wire waveguide can be flexibly transmitted and focused to sub-wavelength dimensions by using, for example, a tapered tip. This is particularly useful for applications that require high-field pulses. However, the generation of strong terahertz surface waves on a wire waveguide remains a challenge. Here, ultrafast field propagation along a metal wire...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

More and more popular electric vehicles are excellent application platforms for steerby-wire (SBW) system. Handling stabilities and active safety are greatly improved when SBW is adopted in electric vehicle. The proposed new architecture of SBW electric vehicle is introduced, its dynamics model is built after the principle and structure. The algorithm achieves the yaw motion of electric vehicle...

In the last years we have witnessed a growing interest, by the academic community and the automotive industry, in the multi-motor electric vehicles. The electrical nature of the propulsion is going to stress even more an increasing insertion of electronic devices in the vehicles. Furthermore, carmakers are performing research and already presented some vehicles based on the concept of X-By-Wire...
