A nuclear power company is currently in the process of constructing the advanced 3rd generation of EPR Nuclear Power Plant, and its corresponding information system is an overall integrated information management system based on the new concept design. The purpose of this report is to research the practice and value of AVEVA IPE solution[2-5] in this nuclear project via the demonstration. And the...
According to the current circumstances, the cultivating and training of the newest armored equipments maintenance support personnel is difficult to meet army's demand all the time, and can't meet the needs of equipments development either, we researched the maintenance training simulation system which is basic to half-practicality and virtual reality technology in chief. We made the overall design...
Armament maintainability engineering is a kind of material practical activity comprising both technical factors and non-technical factors with system integration base, which involves in decision-making, planning, leading, coordination and control etc. However, in the course of promoting armament maintainability engineering in those technology laggard countries, the phenomenon that pay attention to...
Based on the problems appeared in some infantry fighting vehicle's actual training, this paper combines the advantages of virtual maintenance, proceeds from aspect of system engineering, takes demand of actual training into account, uses Solidworks, 3ds max and EON synthetically, chooses the form of desktop, set up a virtual maintenance training system of the equipment.
To reduce the weight of bracket and production cost of the naval gun, the aluminum board welded structure is used. The strength check analysis must be conducted for the fire safety. Firstly, based on the three-dimensional CAD model of the bracket and according to the design date, the geometry of model was simplified. Secondly, the FEM model of the bracket was built with the FEM software MSC. Patran,...
In this paper are presented information about common and advanced materials used for manufacturing of products by Fused Deposition Modelling (FDM) rapid prototyping technology. In different rapid prototyping technologies the initial state of material can come in either solid, liquid or powder state. In solid state it can come in various forms such as pellets, wire or laminates. The current range materials...
Parameter measurement of 3D soft tissue model is of great theoretical significance and application value in virtual surgery training simulation system. To solve the problems of existing soft tissue parameter measurement methods with high complexity, we propose a fast and effective parameter measurement method. We adopt a pillow as test material and exert pressure on it to simulate the parameter measurement...
In this paper, a fast electrical-thermal co-simulation method based on multigrid approach is proposed for simulating 3D systems. Using the proposed approach, accurate voltage/current distribution with temperature effect as well as temperature distribution with Joule heating effect can be obtained efficiently. By ensuring smoothly stretched gridding between die region and package region, fast convergence...
The frame three-dimensional entity model of a formula racing car is established on CATIA software platform, and is analyzed by finite element through the ANSYS software. Through the analysis of the static typical working conditions of the frame (bending and torsion conditions of the frame), find the affluent parts of the strength and stiffness of the frame, reduce the number of pipe fittings and diminish...
The VORPAL finite-difference time-domain particle-in-cell simulation tool now has thermal solver capability, which we are using to model transmission lines and accelerating cavities of cryogenic SRF accelerators. This same capability can be brought to bear on room temperature problems EM and Thermal physics. Our thermal solver treats the non-linear evolution of the material properties, such as electrical...
As novas plataformas semi-submersíveis de grande porte têm sido projetadas com colunas de seção quadrada e arranjo estrutural constituído de painéis planos enrijecidos longitudinalmente. O presente trabalho investiga o comportamento de painéis enrijecidos de um segmento de coluna de plataforma semi-submersível nos regimes pré e pós-colapso. Os painéis enrijecidos são analisados para identificar o...
Creating entertaining and educational books not only requires providing visually stimulating content but also means for students to interact, create, and express themselves. In this paper we present a new type of mixed-reality book experience, which augments an educational coloring book with user-generated three dimensional content. We explore a “pop-up book” metaphor and describe a process by which...
Developing 3D systems is a highly complex procedure. Next to a huge variation of possibilities on how to vertically integrate two or more dies, a lot of aspects regarding cost, design and application specific selection of technology have to be considered. Therefore a design model, considering the mutual influence of design and process technology during the integration flow development and a data management...
Quite a few tasks focusing on failures of electronic components caused by vibrations have shown that a satisfactory depth of problem analysis cannot be achieved with existing problem-solving methods. Thus, new options supported by computing power have been investigated which make evaluating the stress and reliability of electronic components subject to vibrations faster and more reliable. The paper...
In this work we propose a new concept of so called implicit (or "hidden") properties implemented in material object models. These are some features of the material object model that cannot be perceived by the observer through his/her senses (i.e. magnetization, radiation, humidity). Exploration of such features requires additional means and techniques that expand the perception range of...
Something about 1 million skeletal defects are reported each year, which are in need of bone-grafting to be cured. Note that population of the world is getting older and so the probability of bone fractures is increasing, while dealing with this would have lots of social and economical effects. Bone grafts can be both autologous and autogenous or as an alternative, be made of nonorganic materials...
Decision making in industry continues to become more complicated. Customers are more demanding, competition is more fierce, and costs for labor and raw materials continue to rise. Managers need state-of-the-art tools to help in planning, design, and operations of their facilities. Simulation provides a virtual factory where ideas can be tested and performance improved. The AutoMod product suite from...
Frog dissection practice used to be a student's laboratory work in Japanese elementary schools. It was an effective approach for learning animal's anatomy. However this practice has been stopped due to animal protection issues and implemental cost. In this study, we aimed to simulate interactive dissecting practice in the virtual space. The presented virtual frog dissection system consists of virtual...
The design process falls into the problem-solving method in which it involves an intensive way of searching and matching that generates a large solution space. In that sense and inspired on the Kryssanov's design model, this paper introduces a novel design model based on genetic algorithms that aims to achieve an optimal solution taking into account the design objectives, the conceptual design, the...
OpenGL is a commonly used modeling tool in the virtual scene modeling. However, OpenGL graphics library does not provide advanced modeling commands, in this case, it is difficult to create complicated scene models and the models which it created are less realistic. The professional three-dimensional modeling software has strong modeling capabilities, modeling vivid, but it can not meet the interoperability...
