In view of the wide demands sandwich structure with porous material as core layer in many important fields such protection engineering, aerospace, automobile manufacturing and ship, etc. order to reveal energy absorption damage characteristics high velocity impact aluminum foam CFRP/aluminum structure, quasi-static loading system, one-stage light gas gun pressure testing system high-speed camera acquisition were used perform compression experiments projectiles different materials impacting...
The shear thickening fluid (STF) impregnated Kevlar fabric coating glass fiber reinforced plastic (GFRP) composite structure has both wearing comfort and high protective ability, which will provide guidance for the development of new products. In this study, STF with SiO2 mass fraction 34% was prepared, quasi-static/dynamic mechanical behavior STF, GFRP were carried out by high-speed impact experiments, respectively. At same time, damage characteristics energy absorption properties are...
Infrared imaging is essential for detecting multiple unmanned aerial vehicle (UAV) targets detection to capture flight altitude and behavior. This study focused on a typical stealth UAV formation with flying-wing configuration. Considering the attenuation effects of clouds rain infrared spectrum, ground-based algorithm was developed. radiation conducted using apparent ray tracing method mesh clipping technology. The intensity distribution target within 8.0–12.0 μm band calculated, thermal...
High entropy alloy has attracted much attention in the field of national defense due to their excellent low-temperature dynamic mechanical properties. Taking TiZrHfCu0.5 high as research object, compressive properties specimens under quasi-static and (strain rate range 600s-1-2600s-1 temperature -60 °C -20 °C) conditions are systematically tested. Based on static/dynamic stress-strain experimental results, parameters original Johnson-Cook constitutive model determined by fitting. On this...
In order to deeply reveal the microscopic damage mode and mechanism of Carbon Fiber Reinforced Plastic laminates (CFRP laminates) impacted vertically by ice projectile at high velocity. this paper, loading system one-stage light gas gun, liquid nitrogen circulating cooling system, impact pressure measuring speed camera acquisition are used, experiments spherical (simulated hail ice, SHI) with diameter 11 mm impacting CFRP velocity 50-200 m/s were carried out. The SHI target, strain X-Y in...
To profoundly reveal the protective performance of CFRP/aluminum foam sandwich structure, high-speed impact simulation models CFRP, aluminum and their structures are built by ABAQUS/Explicit module. The VUMAT user material subroutine is written for CFRP panel, Hashin damage criterion introduced. elastic constitutive model macro modeling method chosen. process under different working conditions numerically simulated reliability verified one-stage light gas gun loading experiment at...
In order to investigate the energy release behavior of Al/polytetrafluoroethylene (Al/PTFE) reactive materials (RMS) more effectively, a closed chamber test system that could simultaneously examine overpressure and temperature is designed. The maximum with range 2.18–6.74 MPa 1701–2756 K are obtained for 4–10 g RMS powder in confined space 8.8 l. theoretical calculation done internal air (IEA), gas product, solid pressure potential mixture (PPEGM), wall (IECW), total released (TRE), specific...
This article proposes a double-primaries tubular permanent magnet synchronous linear motor (DP-TPMSLM) with low thrust ripple composed of two primaries, secondary, and flux barrier. For DP-TPMSLM, the odd harmonics in detent force can be effectively eliminated by decoupling modulating its cogging end forces. The pole-slot combination winding arrangement proposed are analyzed to realize electromagnetic properties primaries superimposed on each other. selects 12-slot, 11-pole DP-TPMSLM as...
