Based on a systematic investigation the experimental, theoretical and numerical results various tubes under axial compression/impact including our own tests, set of key performance indicators (KPIs) for assessing comparing energy absorbing tubular structures with configurations is proposed, so as to guide design absorbers whilst facilitate parameter optimization. The five KPIs proposed basis mechanical analyses are effective stroke ratio (ESR), nondimensional load-carrying capacity (NLC),...
The proposal of simultaneously determining the hohlraum peak radiation temperature T(R) and M-band fraction f(M) by shock velocity measurement technique [Y. S. Li et al. Phys. Plasmas 18, 022701 (2011)] is demonstrated for first time in recent experiments conducted on SGIII-prototype laser facility. In experiments, are determined using observed velocities Al Ti. For Au used about 160 eV around 4.3% under a 1 ns pulse 2 kJ. results from this method complementary to those broadband x-ray...
In high-speed precision machining, thermal deformation caused by temperature rise affects the accuracy stability of machine tool to a significant extent. order reduce ball screws and improve accuracy, new adaptive method based on carbon fiber reinforced plastics (CFRP) was proposed in this study determined. By using sequential coupling method, thermal–structural analysis screw conducted finite element (FEM). The results were verified through comparison with experimental results. Based...
Many thin-walled structure components widely used in aero industries not only have complex and large size, but also need high machining accuracy. However, because of their poor rigidity, it is easy to bring deformation caused by the existence initial residual stresses, fixing cutting forces heat. The difficulty ensuring accuracy becomes a big problem, so that how effectively predict control has become an important subject development production our national defense weapons. This paper...
In order to obtain the dynamic variation rule of sulfur content liquid steel in LF refining process, a complete mathematical model including desulfurization kinetic and temperature deep process is presented, based on practical production reaction mechanism ultra-low-sulfur LF. The results show that calculated values using fit experimental well, relative error less than 8%. effects slag are analyzed this paper, which shows basicity most important at early middle stages while weight late...
A 1:1 flexible rock shed made of nets and steel‐vaulted structure is manufactured tested for functional evaluation with impact experiment previously. To further discuss the performance this under rockfalls to improve design, numerical simulation carried out in paper. Firstly, simplified models characterizing mechanical behavior ring wire meshes are deduced. Then, a detailed finite element model developed analysis. By comparing experimental data, shown be reliable predicting dynamic shed....
In the local thermodynamic equilibrium approximation, we study problems on low-temperature volume ignition of DT fuel. The temperature and compression threshold are given by solving ion, electric radiation energy equation. ignitions points affected albedo, mass, abundance ratio, etc. At point ignition, reduces with increase areal density. trends variations in electron become closer to each other. most important fact is that subsequent development system can be analyzing stationary solution...
Many thin-walled aero-parts have complex structure, and high machining accuracy is required. But because of their poor rigidity, it easy to bring deformation caused by the existence clamping residual stress, influences workpiece. At present time a focal point how reduce machined surface. Present studies mainly focus on points, order force stresses. It few studied for schemes influence stresses fatigue resistance parts. To reflect relationship between resistance, finite element models with...
The Dugdale model is one of the most famous achievements in fracture mechanics due to its accurate predication size plastic zone at crack tip comparison with experimental results. However, generally used for analysis infinite-width cracked plates, and it has not been successfully extended analytically finite-width which are more commonly seen engineering structures. In this paper, plates was analyzed based on line method. Solving a plate mode-I center broken down into two problems analytical...
This paper presents a statistical Process Control (SPC) method based on Fuzzy ART (adaptive Resonance Theory) neural network. The network is applied to recognize the special disturbance of manufacturing processes classification histograms. It shown that can adaptively learn features histograms quality parameters in processes. As result, be automatically detected when feature starts appear
This paper attempts to replace the traditional manual slag offloading of magnesium smelting in Pidgeon process with robotic removal.Specifically, high-temperature infrared dot matrix was used measure positions indirectly; faster region-based convolutional neural network (Faster R-CNN) trained thermal image reduction jar as dataset; isothermal plotted based on centers, and adopted detect opening direction positions.The indirect measurement results show that actual internal temperature can be...
