摘要
文章分析了使用数字孪生概念研究飞机机翼生产过程中几何参数(GP)变化的结果。创建产品数字孪生的概念是通过在制造的每个关键阶段构建机翼控制台的几何模型来实现的。主要关注点是研究机翼控制台沉箱部分的 GP 在以下阶段的变化:控制台在飞机夹具中的组装、控制台从飞机夹具中取出的组装以及飞机的最终组装。结论是,机翼 GP 的首次显著变化出现在将机翼沉箱从飞机夹具中取出的阶段。结果表明,即使飞机夹具具有可接受的模具成型特性,也不能确保实际机翼 GP 符合允许公差范围内的设计数据,因此不能作为控制 GP 的手段。证明有必要在机翼沉箱制造技术流程中实施一套程序,用于监测从飞机夹具中取出后的装置几何形状。为全面评估隔离单元的几何参数,建议使用飞机的数字模型,该模型是根据单元实际表面的执行模型在产品制造的每个阶段形成的。
Application of the geometric component of a product digital twin when studying its actual geometric parameters
The article analyzes the results of using the digital twin concept to study changes in the geometric parameters (GP) of an aircraft wing during its production. The concept of creating a product digital twin is put into practice by constructing geometric models of the wing console at each key stage of its manufacture. The main attention is focused on studying the change in the GP of the caisson part of the wing console at the following stages: assembling of consoles in an aircraft fixture, assembling of consoles out of an aircraft fixture and final assembling of an aircraft. It is concluded that the first significant changes in wing GP appear at the stage of removing the wing caisson from the aircraft fixture. It is shown that even with acceptable mold forming characteristics of the aircraft fixture, it does not ensure compliance of the actual wing GP with the design data within the permitted tolerances and cannot be a means of controlling GP. It is substantiated the necessity of implementing into a wing caisson manufacturing technological process a procedure for monitoring the geometric shape of the unit after its removal from an aircraft fixture. It is proposed for a comprehensive assessment of isolated units’ geometric parameters to use a digital model of the aircraft, which is formed at each stage of the product manufacturing based on executed models of the units’ actual surfaces.
