为了解决飞机研发过程中,管线路及设备设计自动化程度低的问题。基于CATIA V5进行二次开发,使用API接口和VB语言实现相关工具的搭建,并主要在以下几个方面开展研究:一是在飞机初步设计阶段进行设备的快速布置;二是基于电气设备及周围零部件的空间布置,进行单一DMU管线路通道拓扑,通过EWIS隔离代码定义,规划线束通道的类型,自动分析通道之间的物理隔离距离,并依据EWIS隔离要求规范与自动分析的物理隔离距离进行分析,从而输出全机管线路通道之间的间隙检查结果及分析报告,为后续的通道拓扑优化提供相应的接口及设计规范;三是进行主通道及分支通道拓扑,通过定义通道的直径、通道内布置线缆的规格及不同形式布线的概率,开发工具自动计算EWIS线缆的总长度,并由公式快速计算出该线缆敷设方案的重量,供全机设计时参考。 相似文献

Achieving the United States’ Vision for future Space Exploration will necessitate far greater collaboration between humans and automated technology than previous space initiatives. However, the development of methodologies to optimize this collaboration currently lags behind development of the technologies themselves, thus potentially decreasing mission safety, efficiency and probability of success. This paper discusses the human supervisory control (HSC) implications for use in space, and outlines several areas of current automated space technology in which the function allocation between humans and machines/automation is sub-optimal or under dispute, including automated spacecraft landings, Mission Control, and wearable extra-vehicular activity computers. Based on these case studies, we show that a more robust HSC research program will be crucial to achieving the Vision for Space Exploration, especially given the limited resources under which it must be accomplished. 相似文献

依据"人机协作"理念,提出了一种民用飞机驾驶舱人机功能分配的优化方法,即通过人机系统的功能分类及自动化等级划分、飞行阶段任务分解,对操作程序进行重构并采用专家评价的方法对人机功能分配进行优化与评估。该方法对于大型客机驾驶舱人机界面的设计和飞行员操作程序的制定具有一定的参考价值。 相似文献

Financial pressures are forcing organizations to minimize operations costs. Although the easiest way to achieve this goal is simply to reduce operational requirements, often this is not possible. Therefore, automation must be employed. This paper discusses the system trade-offs that must be performed to maximize the impact of automation efforts. The discussion begins with the development of generic automation guidelines. Since many automation issues are program-specific, the paper addresses the application of these principles to operation of the ORBCOMM satellite constellation. This example demonstrates how automation can be used to produce a highly efficient satellite operations system. 相似文献

Recent developments have seen a trend towards larger constellations of spacecraft, with some proposals featuring constellations of more than 10.000 satellites. While similar concepts for large constellations already existed in the past, traditional satellite deployments hardly ever feature groups of more than 100 satellites. This trend towards considerably larger satellite numbers originates from non-traditional design and operations of spacecraft by non-traditional space companies. The evolution in the space sector, precipitated by new players, is often referred to as “Space 4.0” or “New Space”. It necessitates a rethinking of the way satellites and satellite constellations are planned, designed, and operated. New operational paradigms are needed to enable automatic, optimal task definition, and scheduling in a holistic approach.This is the second of two companion papers that investigate the operations of distributed satellite systems. This second article investigates the classification of distributed satellite systems and evaluates commercial tools for automated spacecraft operations, whereas the first article performed a survey of conventional and “new space”operations of spacecraft constellations.Classification metrics for constellations are derived and evaluated with respect to their informative value concerning the operation, the automation, and the scalability of the constellation. The proposed classification system is applied to the Dove and RapidEye constellation and allows for a comparison between the presented automation approaches. Commercial tools for automated spacecraft operations are evaluated for several mission task elements, such as orbit control, orbit maintenance, and collision avoidance. Subsequently, the trends, benefits, and standardization needs for operational automation are identified. 相似文献
