With the progress of computer technology and the improvement of engineering technology , traditional design method has not been suitable for the requirements of the development 随着工程技术要求的逐渐提高,以及计算机技术突飞猛进的发展,传统的手工作图法已不适应当今发展的需要。
It is rapidly modifying and fabricating the eccentric - sleeve press by means of illustration , with less quantity of modified parts and shorter time , which can fulfill the requests of the clients to the delivery - date and the process 摘要采用作图法快速改制固定式偏心套压力机,改制工件少,时间短,及时满足用户对产品交货期及工艺的需求。
Using visual lisp language to calculate and verify is a breakthrough . according to it , we can get the protection area of lightning rod with the fealures of random number , different height and asymmetry layout 用visuallisp语言来计算、校验避雷针的保护范围,可以同时实现任意多支、不等高、不对称布置的避雷针的保护范围,是传统手工作图法的一个新突破。
On this condition the thesis proposes the computer aided design method about the protection area of lightning rod . on the basis of the forming principle , basic characteristics and main harm of lightning , this thesis firstly introduces the development of lightning protection , then discusses the principle of lightning rod protection and the calculation method of protection area through the analysis and introduction to additional calculation method ? electrical geometry construct , an improved measure is put forward in this paper 本文就是在此基础上,提出了对避雷针保护范围的计算机辅助设计。本文从雷电的形成、基本特点及其主要危害出发,简要介绍了防雷技术的发展过程,对避雷针保护的原理及保护范围的计算方法做出了较详细的阐述。通过对避雷针保护范围传统计算方法(电气几何作图法)的分析、介绍,提出了对该方法的改进措施。
