Optimal haulage routing of off-road dump trucks in construction and mining sites using Google Earth and a modified least-cost path algorithm 总被引:2,自引:0,他引:2
This study presents new software, called Google Earth-based Optimal HAulage RouTing System (GEOHARTS), to improve the functionality of Google Earth for optimal haulage routing of off-road dump trucks in construction and mining sites. A modified least-cost path algorithm, which is applicable to working areas with both paved and unpaved temporary roads and can consider the effects of terrain relief and curves along a route on the route planning, was proposed and utilized for the software development. GEOHARTS can determine optimal haulage routes between loaders and dumps that ensure the least travel time or fuel consumption of off-road dump trucks and can visualize the results using an embedded 3D render window of Google Earth. The application to the Pasir open-pit coal mine in Indonesia demonstrates that GEOHARTS could provide a rational solution to support the truck haulage operations. 相似文献

面对以太阳能为代表的城市新能源供给系统正在从单向集中模式走向双向分散模式的历史性变革,城市规划与建筑设计领域也随之催生了一批关于新能源的研究。而其中工作尺度介于这两者之间的城市设计,因其操作对象的三维形态特征,能够有效地将城市规划中对土地太阳能潜力的预测,与建筑设计中对太阳能建筑一体化构件的设计贯穿起来。由此,文中展示了如何运用参数化的生成与评价技术,按照城市设计中的三维形态、日常设计中各种建筑类型的经验数值、太阳能采集单元的安装规范等限制条件,对城市设计方案进行自动地太阳能采集设备单元模拟安装,即生成了各种尺度、位置的太阳能采集单元基面,并自动地完成对于方案的太阳能采集能力的定量化评估,以此实现对城市设计方案间的比较,以及对后续建筑设计中造型取舍的引导。 相似文献

Recent advances in computer tools have improved the ability to store, navigate and display large and complex three-dimensional (3D) models, a step forward in architectural and urban planning. The generation of photo-realistic models is a time-consuming task that requires significant human input, despite current developments in photogrammetry and 3D scanning technology. Though computer vision techniques operate automatically, they do not produce usable models, frequently being weak with respect to occlusion and changes in illumination, on top of operating with small sets of images. To solve these limitations, this research work uses a new biologically based system, called BioCAD, which mimics the human vision process. This novel system is specifically designed for the rapid and accurate generation of 3D computer models from existing large objects, like buildings, allowing a direct link to rapid prototyping systems. A World Heritage building was chosen as a case study to validate BioCAD. 相似文献

Design as scholarship or scholarship of design? "No" to a forced choice of ideology but "yes" to a new model of architectural critical theory. These twinned aspirations of scholarship are frozen by ideological mandates that control signification and visualization. First, we must understand how ideology creates metaphors in teaching and research; then, we must spatialize this same logic to see the inner workings of our synesthetic experience of architectural space as an act of reception. 相似文献

Variable complexity design of composite fuselage frames by response surface techniques 总被引:1,自引:0,他引:1
Curved frame structures are often used as part of the internal skeletal structure in aircraft. Laminated composite materials offer potential weight savings for such structures, but composite frames have different and more complex failure mechanisms than metallic frames. In particular, failure mechanisms involving interlaminar stresses are important in composite structures. Interlaminar stresses can be directly computed from three-dimensional finite element models, but the computational expense of these models is prohibitive. In this work, two- and three-dimensional (2D and 3D) finite element models are combined to reduce the computational expense associated with designing composite frames. A response surface design approach is used to approximate the failure response of curved composite C-section frames subjected to an axial tensile loading using a minimum number of finite element analyses. Results are presented for two examples with two and five design variables, respectively. 相似文献
