Aiming at the difficulty of large weapon equipment operation training simulation, GL Studio software tool was adopted based on VR technology. A hierarchy structure was put forward to simulate all kinds of integrating equipment system, single equipment and operation unit. Key technologies including Model database structure optimization, LOD, operation unit motion simulation based on DOF and screen...
The general design of HLA based communication command equipment operation simulation system is given to solve the difficulty of large equipment operation training. Firstly, the simulation system and its constitution are introduced. Secondly, two different federation runtime structures including single federation basic structure and multiple federations structure are designed according to system architecture...
The enormous computational power available in modern graphics processing units (GPUs) has enabled the widely use of them for general-purpose applications. However, manual development of high-performance parallel codes for GPUs is still very challenging. In order for improving GPGPU application performance by efficiently using GPU global memory, we extend the polyhedral model to capture memory access...
Taking full account of the liquid viscosity, surface tension and other factors, a detailed numerical simulation using VOF method was carried out to study the dynamic behavior of bubbles in still water, and obtained the rising path, deformation process and speed changes. The numerical results were compared with experimental data, and gained good result. It shows the results of this study can provide...
There are many experiments to be carried out inevitably in science research. How to arrange experiment plans, and how to determine the influence of each parameter to results. The method to solve those questions is experiment design. In present work the orthogonal experimental design method is adopted to arrange experiments of drop test for conical shell, and analyze the sensitivities of some parameters...
The current military simulative training didn't consider the impact of battlefield communication network well, so it can't meet the requirement of future development. To solve this problem, the paper put forwarded the new idea of military simulative training based on "network in the loop". Through the utilizing of high level architecture (HLA), network simulation technology and etc, we embedded...
