【摘要】：飛機(jī)裝配過(guò)程復(fù)雜、工作量大,是飛機(jī)制造中的重要一環(huán),飛機(jī)裝配工藝設(shè)計(jì)合理與否決定了飛機(jī)裝配質(zhì)量的好壞。目前國(guó)內(nèi)的飛機(jī)裝配工藝設(shè)計(jì)仍主要采用數(shù)字量與模擬量相結(jié)合的傳遞模式,工藝文件主要以傳統(tǒng)的二維方式進(jìn)行表示和發(fā)放,工藝信息表達(dá)不直觀,工藝更改過(guò)程繁瑣。為此,針對(duì)企業(yè)迫切需要展開(kāi)三維可視化裝配工藝的實(shí)際需求,引入MBD(Model Based Definition)技術(shù),基于DELMIA平臺(tái),研究飛機(jī)產(chǎn)品的三維可視化裝配工藝設(shè)計(jì)技術(shù)。主要研究工作如下:首先通過(guò)對(duì)飛機(jī)裝配工藝設(shè)計(jì)的內(nèi)容和設(shè)計(jì)流程進(jìn)行分析、總結(jié)和歸納,將裝配工藝信息分為三類:產(chǎn)品、工藝和資源。采用MBD技術(shù),建立產(chǎn)品-工藝-資源模型,用于描述產(chǎn)品結(jié)構(gòu)、工藝設(shè)計(jì)與工藝資源的詳細(xì)內(nèi)容以及三者之間的內(nèi)在聯(lián)系。為基于數(shù)字量的工藝信息傳遞奠定基礎(chǔ)。其次以DELMIA為平臺(tái),完成產(chǎn)品模板、工藝模板和資源模板的定制,建立裝配工藝規(guī)劃結(jié)構(gòu)樹(shù),明確三維可視化裝配工藝設(shè)計(jì)流程。再次,制定了三維可視化環(huán)境下的通航飛機(jī)產(chǎn)品裝配仿真流程,實(shí)現(xiàn)了裝配序列、裝配路徑和人機(jī)工程仿真,并給出了驗(yàn)證產(chǎn)品設(shè)計(jì)、工裝設(shè)計(jì)以及裝配工藝規(guī)劃的合理性的方法。最后以某機(jī)型框組件的裝配工藝設(shè)計(jì)為例,建立了該組件裝配工藝規(guī)劃模型,實(shí)現(xiàn)了三維可視化環(huán)境下的裝配工藝規(guī)劃與仿真。結(jié)果表明,運(yùn)用上述研究方法和技術(shù),能夠更加直觀、快捷的完成工藝設(shè)計(jì)工作,滿足企業(yè)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.
