1.概述计算机辅助结构设计包括两方面的内容:一是用计算机绘制工程图纸,二是用计算机对结构进行力学分析。在结构设计中,当初始设计方案确定后,大量的工作是用工程图表达出设计者的设计思想,以便让工人按图纸加工出实物。为了表达清楚一个飞航导弹的结构情况,往往需要画出几千张,甚至上万张(A4图)图纸。画工程图,既是严谨的脑力劳动,又是繁重的体力劳动。随着计算机的广泛应用和计算机绘图软件包的飞速发展,开辟了计算机图形设计这个新的技
1. Overview Computer-aided design consists of two aspects: First, the use of computer engineering drawing drawings, the second is the mechanical analysis of the structure of the computer. In the structural design, when the initial design is finalized, a great deal of work is to use the engineering drawings to express the designer’s design idea so that the workers can process the physical objects according to the drawings. In order to clearly understand the structure of a missile, it is often necessary to draw thousands or even tens of thousands of drawings (A4 drawings). Painting drawings, both rigorous mental work, but also heavy manual labor. With the widespread use of computers and the rapid development of computer graphics packages, the new technology of computer graphics has been opened up
