【摘要】：飞机装配过程复杂、工作量大,是飞机制造中的重要一环,飞机装配工艺设计合理与否决定了飞机装配质量的好坏。目前国内的飞机装配工艺设计仍主要采用数字量与模拟量相结合的传递模式,工艺文件主要以传统的二维方式进行表示和发放,工艺信息表达不直观,工艺更改过程繁琐。为此,针对企业迫切需要展开三维可视化装配工艺的实际需求,引入MBD(Model Based Definition)技术,基于DELMIA平台,研究飞机产品的三维可视化装配工艺设计技术。主要研究工作如下:首先通过对飞机装配工艺设计的内容和设计流程进行分析、总结和归纳,将装配工艺信息分为三类:产品、工艺和资源。采用MBD技术,建立产品-工艺-资源模型,用于描述产品结构、工艺设计与工艺资源的详细内容以及三者之间的内在联系。为基于数字量的工艺信息传递奠定基础。其次以DELMIA为平台,完成产品模板、工艺模板和资源模板的定制,建立装配工艺规划结构树,明确三维可视化装配工艺设计流程。再次,制定了三维可视化环境下的通航飞机产品装配仿真流程,实现了装配序列、装配路径和人机工程仿真,并给出了验证产品设计、工装设计以及装配工艺规划的合理性的方法。最后以某机型框组件的装配工艺设计为例,建立了该组件装配工艺规划模型,实现了三维可视化环境下的装配工艺规划与仿真。结果表明,运用上述研究方法和技术,能够更加直观、快捷的完成工艺设计工作,满足企业需求。
[Abstract]:The assembly process of aircraft is complex and the workload is large, which is an important part of aircraft manufacturing. The quality of aircraft assembly is decided by the reasonable design of aircraft assembly process. At present, the domestic aircraft assembly process design still mainly adopts the transfer mode of the combination of digital quantity and analog quantity, the process file is mainly expressed and distributed in the traditional two-dimensional way, the process information expression is not intuitionistic, and the process of process change is complicated. Therefore, aiming at the actual demand of 3D visual assembly process, MBD (Model Based Definition) technology is introduced to study the 3D visual assembly process planning technology of aircraft products based on DELMIA platform. The main research work is as follows: firstly, through the analysis of the content and design process of aircraft assembly process design, the assembly process information is divided into three categories: product, process and resources. The product-process-resource model is established by using MBD technology to describe the product structure, the detailed contents of process planning and process resources, and the internal relations among them. It lays the foundation for the process information transmission based on digital quantity. Secondly, using DELMIA as the platform, the customization of product template, process template and resource template is completed, the assembly process planning structure tree is established, and the 3D visual assembly process planning flow is clarified. Thirdly, the simulation flow of aeronautical aircraft product assembly in 3D visual environment is established, and the assembly sequence, assembly path and ergonomics simulation are realized, and the verification product design is given. A reasonable method for tooling design and assembly process planning. Finally, taking the assembly process planning of a frame component as an example, the assembly process planning model of the component is established, and the assembly process planning and simulation under the three-dimensional visual environment is realized. The results show that the process design can be completed more intuitively and quickly by using the above research methods and techniques to meet the needs of enterprises.
