CATIA, as the main design software of the flight simulator display system, can complete the structure design of display system; find the rationality of structure design by the virtual assembly; do some appropriate changes to achieve the optimal solution.
Bringing immersive and interactive visualization experiences to end users without requiring them physical presenting onsite, web based virtual reality applications have been successful in many domains. Because of the still limited computing resources of the web clients, interactive navigating through virtual scenes with complex geometric data model becomes a bottleneck in the application. Meanwhile,...
In order to model the gearbox and global wind turbine system with higher accuracy in short time, this paper focuses on the methods of multi-body dynamic modeling and wind turbine dynamic simulation on the platform of S4WT. By introducing the multibody system and super element approach, a steady-state response is simulated on one 1.5MW gearbox. Through calling S4WT parametric model, a dynamic response...
Helix is widely used in industrial modeling. Characteristic parameterization and modeling are based on helix parameterization. However, helix cannot be accurately represented by NURBS, and no helix interface for UG secondary development. It is difficult for modeling parameterization based on helix. This paper proposed a novel modeling method by using NURBS approximating helix, and presented the error...
The phase field method is an effective method on solidification microstructure simulation. In this paper, the basic principles and the phase field model are introduced respectively. And then, the applications of phase-field simulation on solidification microstructure are summarized briefly. Finally, the problems to be faced and the future development trends are pointed out in this area.
Through analyzing the effect factors of error in rapid glass mould manufacturing process, the rapid tooling precision control system has be researched. Using of computer simulation of metal casting process to compensate size changes, and using electrical discharge machining eliminate mold roughcast making process of size change, the rapid mould manufacturing process chain error can be considered as...
In the virtual reality technology, simulate the different weather can increase the realism, the particles of the rain and snow is usually realized by the particle system. While, when the particles reach to certain orders of magnitude. It is difficult to achieve real-time effects. LOD technology means control of details, based on the research of particle system and LOD technology, the author puts forward...
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 paper introduces the graphic technology in ocean environment visual simulation. The simulation model of entity object, climate in sky, sea natural environment were described in detail. These models can simulate ocean environment in real-time and generate realistic scene. And the illumination model, LOD model and multilevel texture mapping were researched to improve the rendering efficiency. The...
The Access Grid (AG) is one of the most widely used technologies for building advanced collaborative environment, and a distributed collaborative Augmented Reality (AR) environment has been established with AG and AR technologies. In such distributed shared environment, one of the most difficult tasks is maintaining a consistent view of the shared AR scene among all participants. This paper presents...
