C4ISR系统需求模型

目前军事需求的描述方法主要是理论研究为主,无法较好应用于我军的需求开发实践.根据我军联合作战指挥信息系统的需求开发经验,提出了一种可行的C4ISR需求描述模型,首先分析了需求建模所涉及的要素及其关系,提出了C4ISR需求模型的概念,然后以图形化和形式化两种形式分别对用户模型、活动模型、信息模型和功能模型等4个方面进行了需求描述方法的研究.     

C4ISR中基于XML的作战文书标准化

作战文书标准化是C4ISR系统中实现作战文书自动处心技术在作战文书标准化中的实际应用用DTD规定作战文书的逻辑结构、用XML语言描述作战文书的内容、用XSL规范作战文书的格式;进而根据作战文书的处理流程,提出了作战文书标准化系统的三层整体架构作战文书产生层、网络传输层、作战文书接受层.

Experimental and numerical investigations of interface properties of Ti6Al4V/CP-Ti/Copper composite plate prepared by explosive welding

Explosive welding technique is widely used in many industries. This technique is useful to weld different kinds of metal alloys that are not easily welded by any other welding methods. Interlayer plays an important role to improve the welding quality and control energy loss during the collision process. In this paper, the Ti6Al4V plate was welded with a copper plate in the presence of a commercially pure titanium interlayer. Microstructure details of welded composite plate were observed through optical and scanning electron microscope. Interlayer-base plate interface morphology showed a wavy structure with solid melted regions inside the vortices. Moreover, the energy dispersive spectroscopy analysis in the interlayer-base interface reveals that there are some identified regions of different kinds of chemical equilibrium phases of Cu–Ti, i.e. CuTi, Cu₂Ti, CuTi₂, Cu₄Ti, etc. To study the mechanical properties of composite plates, mechanical tests were conducted, including the tensile test, bending test, shear test and Vickers hardness test. Numerical simulation of explosive welding process was performed with coupled Smooth Particle Hydrodynamic method, Euler and Arbitrary Lagrangian-Eulerian method. The multi-physics process of explosive welding, including detonation, jetting and interface morphology, was observed with simulation. Moreover, simulated plastic strain, temperature and pressure profiles were analysed to understand the welding conditions. Simulated results show that the interlayer base plate interface was created due to the high plastic deformation and localized melting of the parent plates. At the collision point, both alloys behave like fluids, resulting in the formation of a wavy morphology with vortices, which is in good agreement with the experimental results.
