本文研讨了计算机辅助设计和制造系统(CADAM)中的交互式计算机绘图系统的发展。从概念设计至产品支援整个设计过程中,自始至终一直使用这系统。在概念设计阶段,主要生成三面图。这些图可迅速并准确地转换成三维数学面定义。根据此信息,半自动地生成分析数据模型,以便输入批处理计算程序。分析模型研究的主要领域包括:飞行任务参数分析、气动阻力模型、结构有限元模型、1g载荷和质量分布模型、燃油箱和容积分析、重量和平衡模型。 This article explores the development of interactive computer graphics systems in Computer Aided Design and Manufacturing Systems (CADAMs). From conceptual design to product support throughout the design process, this system has been used throughout. In the conceptual design phase, the main three-dimensional map. These figures can be quickly and accurately converted into three-dimensional mathematical surface definitions. Based on this information, an analytical data model is generated semi-automatically for input to the batch calculation program. The main areas of analytical model research include: mission mission parameter analysis, aerodynamic drag models, structural finite element models, 1g load and mass distribution models, fuel tank and volumetric analysis, weight and balance models.
