过渡协调模式下机翼数学模型的建立

讨论了飞机制造模式由模拟量协调体系向数字量协调体系转化过程中出现的问题,重点研究了其中的关键技术,即飞机外形数字化模型的建立,主要包括理论图的分析与转化,外形数据的获取,翼型轮廓曲线的计算,外形曲面的重构以及误差检验等。上述建模过程遵循了原始设计意图,保证所建数模符合生产中使用的制造与检验依据,为定型飞机数字化建模提供了理论指导。

Establishing of wings mathematic model in transitional coordination mode

Problems appeared in the process of transforming aircraft manufacture mode from simulative information coordination system to digital information coordination system are discussed and researched.The key problem is how to set up aircraft digital model.Main contents includes analyzing and transforming of drawings,extracting of shap data,calculating of wing section's contour curves,reconstructing of shape surfaces and inspection of errors.Above modeling process complied with initial design intensions guarantees that mathematic model set up by this method can be compatible with existing producing and inspection references,and provides academic guidance to existing aircraft modeling method.
