Abstract Optical imaging systems have greatly extended human visual capabilities, enabling the observation and understanding of diverse phenomena. Imaging technologies span a broad spectrum wavelengths from x-ray to radio frequencies impact research activities our daily lives. Traditional glass lenses are fabricated through series complex processes, while polymers offer versatility ease production. However, modern applications often require lens assemblies, driving need for miniaturization...
The suspension point indicator diagram of the beam pumping unit is an essential basis for judging operating conditions unit. It common to use electrical parameters invert diagram. However, current methods using have problems low accuracy and poor practicability. Based on this, method inverting based power-to-load transfer coefficient proposed in this paper. calibrated by measured instantaneous output power motor load. Then Fourier series used fit coefficient. load calculated measuring motor,...
Radio frequency interference (RFI) significantly hampers the target detection performance of frequency-modulated continuous-wave radar. To address problem and maintain echo signal, this paper proposes a priori assumption on component nature in radar received as well method for estimation mitigation via time–frequency analysis. The solution employs Fourier synchrosqueezed transform to implement radar’s beat signal transformation from time domain domain, thus converting task distribution image...
Abstract Thermoset materials, known for their stable topology structure, have garnered significant interest in recent years applications coatings, foam, adhesives, and other fields. In general, the low chemical crosslinking density of thermoset materials means poor mechanical properties. this study, we adjusted topological structure elastomers through formula design controlled hard segment content at same level. The tensile test results show that as elastomer decreases, fracture strength...
A Berkovich indentation test was performed in a single primary α-phase grain of an equiaxed TC6 titanium alloy, to reveal the complex local lattice-rotation process under nano-indentation loading. Numerical simulations using in-house-developed crystal plasticity finite element method code were also conducted. high-resolution inverse pole figure slice across nano-indention obtained via focused ion beam technique coupled with precession electron diffraction. The simulation results corresponded...
The scanning electron microscope (SEM) and backscatter diffraction (EBSD) were used for a quasi in-situ observation on the slip trace crystallographic orientation at four strains during compression of widmannstätten-structure α/β titanium alloy. previous investigations suggested that always initiated in lamellar α prior to interlayered β due lower yield strength higher Young's modulus HCP phase. Interestingly, it is found initiates within colony this work. Meanwhile, preferential initiation...
The penetration of a 30CrMnMo ultra-high molecular weight polyethylene armor by high-speed fragment was investigated via experiments and simulations. Analysis the projectile revealed that nose (of projectile) is in non-equilibrium state at initial stage penetration, low-speed regions undergo plastic deformation. Subsequently, nose-tail velocities were virtually identical fluctuated together. In addition, effective combination steel plate (PE) laminate resulted energy absorption PE just...
Soil liquefaction would cause significant damage to the safety of cargo transportation. The aim this article is conduct a quantitative study influence main physical characteristic parameters saturated sand and external loads on its liquefaction. On basis cyclic triaxial test (CTT), finite element simulation model PSO-BP neural network prediction importance analysis were optimised in study. Based this, an innovative intelligent numerical CTT system for was constructed. research results...
