【摘要】：航天任务可视化是航天仿真的热门研究领域,本文在课题组多年的航天任务可视化仿真基础之上进行航天器飞行可视化研究,探究如何实现一个用于表现航天器飞行可视化的通用框架,侧重于研究实现良好的通用性和可扩展性,以便将其再应用到课题组的工程实践之中。论文在分析国内外相关研究现状之后,就以下几个方面进行了讨论:首先,简要介绍了框架已采用或拟采用的成熟软件工程技术,从软件工程的视角运用这些成熟技术对可视化开发平台进行了深入的分析,以资借鉴。其次,引入了航天器飞行过程可视化涉及到的航天领域关键知识,从面向对象的角度对飞行过程进行了可视化仿真建模,给出了领域模型。然后,分析了课题组现有框架面临的挑战与存在的不足,针对性地提出了改进策略和框架设计应有的原则,运用体系结构和多线程技术进行了新的应用架构设计。最后,运用成熟、合适的软件工程技术对框架多个具体的实现方面进行了深入的分析,给出了改进后的设计。特别地,以物理场可视化为例在通用性和扩展性方面进行了论述。
[Abstract]:Space mission visualization is a hot research field in space simulation. This paper explores how to implement a general framework for the visualization of spacecraft flight, focusing on the research and implementation of good generality and extensibility, so that it can be applied to the engineering practice of the research group. After analyzing the current research situation at home and abroad, the following aspects are discussed: firstly, the mature software engineering technology which has been adopted or is to be adopted by the framework is briefly introduced. From the perspective of software engineering, the visual development platform is deeply analyzed by using these mature technologies for reference. Secondly, the key knowledge of spacecraft flight process visualization is introduced, and the visual simulation model of flight process is established from the point of view of object oriented, and the domain model is given. Then, the challenges and shortcomings of the existing framework of the research group are analyzed, and the improvement strategy and the principle of the framework design are put forward, and the new application architecture is designed by using the architecture and multi-thread technology. Finally, the application of mature and appropriate software engineering technology to the framework of a number of specific aspects of the in-depth analysis of the implementation of the improved design. In particular, taking physical field visualization as an example, generality and expansibility are discussed.
