【摘要】：随着虚拟现实技术的发展，虚拟装配作为虚拟现实技术在制造业中的重要应用之一也随之快速发展起来，它为解决产品的装配问题提供了一个新的低成本、高效率的途径。装配信息是虚拟装配技术的基础，它贯穿于整个虚拟装配过程，直接影响虚拟装配的质量和效率。对装配信息进行统一的管理，可以使装配信息及时、有效、流畅的在各环节之间传递，满足各个环节的需求，是实现虚拟装配的保证。在此背景下，本论文开发了一套虚拟装配信息管理系统，并对其中涉及到的关键技术进行了研究。本文首先通过分析系统的功能需求，采用面向对象的方法设计了系统的整体结构框架，介绍了系统的工作流程，并对系统采用的关键技术做了简要说明。在分析虚拟装配系统对装配信息需求的基础上，本文建立了一个信息完整、结构完善的基于层次结构的混合装配信息模型，满足了完备性、集成性、高效性的要求，同时为了满足数据库对信息数据管理的需要，建立了以关系数据模型为基础的装配信息数据模型。根据建立的装配信息模型以及信息源的不同，本文提出了三种不同的方式获取装配信息，即基于CAD系统的获取、用户的输入和装配过程的智能规划，同时对不同的信息获取方式涉及到的关键技术进行了研究。然后利用数据库技术实现对装配信息的管理，根据装配信息数据模型建立了信息数据表，对获得的装配信息进行储存，进而实现对装配信息进行查询、修改、删除以及其他装配信息的输入，实现对装配信息的动态管理。最后本文对系统进行软件实现，并采用具体的实例验证系统的有效性和可行性，，证明虚拟装配信息管理技术的正确性。
[Abstract]:With the development of virtual reality technology, virtual assembly, as one of the important applications of virtual reality technology in the manufacturing industry, has developed rapidly. It provides a new low-cost and efficient way to solve the assembly problem of products. Assembly information is the foundation of virtual assembly technology. It runs through the whole virtual assembly process and directly affects the quality and efficiency of virtual assembly. The unified management of assembly information can make assembly information timely, effective and smooth, meet the needs of each link, and is the guarantee to realize virtual assembly. In this context, a virtual assembly information management system is developed, and the key technologies involved in it are studied. In this paper, by analyzing the functional requirements of the system, the overall structure of the system is designed by using the object-oriented method, the workflow of the system is introduced, and the key technologies used in the system are briefly explained. On the basis of analyzing the requirement of assembly information in virtual assembly system, this paper establishes a complete and well-structured hybrid assembly information model based on hierarchical structure, which meets the requirements of completeness, integration and efficiency. In order to meet the needs of database for information data management, the assembly information data model based on relational data model is established. According to the different assembly information models and information sources, this paper proposes three different ways to obtain assembly information, that is, acquisition based on CAD system, user input and intelligent planning of assembly process. At the same time, the key technologies involved in different information acquisition methods are studied. Then the assembly information management is realized by using database technology. According to the assembly information data model, the information data table is established, and the assembly information is stored, and then the assembly information is queried and modified. Delete and other assembly information input to achieve the dynamic management of assembly information. Finally, the software implementation of the system is carried out, and the validity and feasibility of the system are verified by a concrete example, which proves the correctness of the virtual assembly information management technology.
