In view of the narrow installation space high power density and torque in-wheel motor, heat existed motor is balanced by cooling water channel to ensure dissipation motor. this paper, Ansoft Maxwell software used establish two-dimensional loss simulation model winding loss, stator core rotor permanent magnet eddy current are calculated respectively. The temperature field calculation established. exchange coefficient calculated, equivalent treatment windings carried out. spiral selected cool...
Harmonic currents can intensify transformer vibrations, seriously threatening their mechanical stability and safe operation. Drawing upon this foundation, the present paper undertakes a thorough simulation experimental investigation into vibration characteristics of transformers under diverse harmonic current scenarios. Initially, multi-field coupling model incorporating both “electromagnetic structural forces” was developed to simulate analyze how acceleration is distributed varying...
The behaviours of laser welding wrought magnesium AZ31B alloy with oxide activating fluxes (TiO 2 , SiO and Cr O 3 ) were studied in the present paper. results showed that three all can increase weld penetration welding. A larger grain size was exhibited metal prepared flux than fusion zone without by optical microscopy. Oxide particles found electron probe microanalysis (EPMA), when used. tensile tests has nearly 90% base strength compared to ones flux. mixed mode fracture main mechanism...
A numerical analysis of electromagnetic (EM) scattering characteristics a hypersonic aerocraft enveloped by plasma sheath is presented. The flow field parameters around are derived numerically solving the Navier-Stokes equations. Through multiphysics coupling and field, distributions frequency collision in sheaths obtained. high-order auxiliary differential equation finite-difference time-domain algorithm employed to investigate EM wave properties covered sheath. backward radar cross...
In this paper, we generalize the method of moments (MOM) based on surface integral equation (SIE) to investigate scattering properties complicated shaped biological cells illuminated by a Laguerre-Gaussian beam (LGB). We introduce Lorentz-gauge vector potential with slowly varying envelope amplitude which satisfies paraxial wave obtain electric and magnetic field components incident beam. The SIE is applied compute arbitrary cells, MLFMA utilized efficiently solve resulting matrix equations,...
Interaction zones resulting from the dual-incident shock wave/turbulent boundary layer interactions (D-ISWTBLI) typically exhibit one of two distinct flow patterns: formation isolated small-scale interaction following decoupling or presence a coupled large-scale zone. This paper investigates underlying mechanism governing transition field D-ISWTBLI, shifting pattern to an one. To achieve this, we employ numerical simulations and propose criterion for determining critical condition. Our study...
Preload optimization is very important for ultrasonic motors’ design and application. In this paper, a novel method traveling-wave rotary motor proposed. Firstly, based on linear regression the analytic hierarchy process (AHP), mapping between drive characteristics, mechanical speed stability, preload of traveling-wave-type was established. Then, characteristic curves stalling torque, no-load speed, maximum efficiency, stability with change were measured new test platform. Finally, three...
ABSTRACT In order to study the influence of tunnel construction on ground settlement in sand, distribution and variation characteristics during were explored through model tests. The results showed that variations surface at different depths basically same monitoring section. settlements along width length directions same. loss increased power function from underground. maximum coefficient trough strongly positively correlated with loss. Based experimental statistical analyses, relation...
The hypersonic flow field around a reentry vehicle has significant influence on the ground-vehicle communication as well detection and recognition of vehicle. Backward scattering characteristics enveloped by are analyzed using high-order auxiliary differential equation finite difference time-domain (ADE-FDTD) method in this paper. Flow parameters, including electron density, neutral particle temperature, obtained solving Navier-Stokes (NS) equations numerically. According to distributions...
