Amino-1,2,4-triazole and amino-1,3,4-oxadiazole substituted 1-hydroxytetrazole derivatives were synthesised via a simple method. These compounds exhibited excellent detonation performance stability owing to their high density heat of formation, extensive...
The effects of different high-altitudes on the blast parameters—including peak overpressure and specific impulse—produced by a center-initiated cylindrical charge (CC) were simulated using AUTODYN software analyzed through dimensional analysis theory. relational equations parameters under reduced temperature pressure developed validated numerical simulations. results demonstrate that are effective in assessing generated CCs conditions temperature, diminished pressure, high-altitude...
Ti/Fe clad plate had attracted extensive attention because of its important application. In order to reduce the titanium layer thickness, explosive welding TA1 foil Q235 steel was carried out. The interfacial bonding performance analyzed by micromorphology analysis and mechanical property test, formation process wave molten block in vortex simulated smoothed particle hydrodynamics (SPH) method. results showed that salt as pressure transfer used could play a good buffer effect on collision...
Abstract To increase the efficiency of deep-hole blasting driving in mine rock tunnels, an innovative pattern wedge cutting with hole-inner delay was proposed. First, mechanisms conventional and patterns were theoretically investigated. The results showed that resistance from large upper blocks clamping action surrounding major challenges methods. For pattern, under conversion spatial distribution release sequence energy, first charge can strengthen breaking mass create a new free surface,...
Four new dry water fire extinguishing agents (FEAs) were developed by hydrophobic SiO<sub>2</sub> and aqueous solution. Among them, FEA with ammonium dihydrogen phosphate has the best effect via temperature changes thermocouples.
AbstractStick–slip vibration is simultaneously influenced by several factors that share complicated coupling relationships. In this research, an experimental investigation was performed to analyze the evolution law of stick–slip characteristics at different working conditions using a tribometer. The results showed disc rotational speed and normal force had noticeable impact on both coefficient friction (COF). Then Stribeck model, which can characterize COF in process, employed parameters...
Inspired by the difference in friction radii of pads from high-speed train brake system, stick–slip experiments for a disc–block system with different were carried out via test device. Based on results, vibration characteristics variation radius analyzed, and corresponding Stribeck model parameters exponential fractional forms identified. The experimental results show that an increase amplitude first increased then decreased frequency increased. identified decay factors increased, static...
The direct synthesis of 1,2-pentanediol (1,2-PeD) from renewable xylose and its derivatives derived hemicellulose is appealing yet challenging due to low selectivity for the target product. In this study, one-pot catalytic conversion 1,2-PeD was performed by using nitrogen-doped carbon (NC) supported Pt catalysts with assistance organic acids. A remarkable yield 49.3% achieved reacting 0.1869 g in 30 mL water at 200 °C under a hydrogen pressure 3 MPa 8 h presence 0.1 2.5Pt/NC600 catalyst...
Traditional emulsion explosives, in spite of excellent water resistance, safe handling and good storage performance, have low power problems which seriously hinders their use. In order to improve the a hydrogen based explosive was devised. Scanning electron microscope pictures experimental results show that coating effect stability coated magnesium hydride (MgH2) are very good. The an sensitized by glass microballoons significantly increased (24.30 mm compression lead block) after adding...
There are many unstable factors in the working environment of electrical workers, which threaten their safety. Therefore, how to protect workers is a problem worth thinking about. Safety helmet protects worker's head from injury when they fall. This paper presents method detect whether wear safety or not. based on Support Vector Machine (SVM), grids Histograms Oriented Gradient (HOG) features, and color features. Firstly, we get information about work scene image. According acquired image,...
