本文是《分块解法在天线背架结构计算中的一个应用》一文的继续。着重介绍在计算机外存容量较小的情况下,使用小机器求解大题目的分块直接解法Ⅱ,由于采用了控制参量,可大大降低对外存的依赖程度,它甚至可在没有外存的情况下继续算题,这在中小型国产机上,用有限单元法分析大型结构有时是很有用处的。文中回顾了分块解法的基本思想,比较了二种分块解法,並给出分块解法Ⅱ的程序框图。在文末附录中提供了用ALGOL—60语言编写的分块解法Ⅱ的过程序段。文中给出用分块解法Ⅱ编写的环梁式天线空桁背架结构分析程序在DJS—21机上考题结果,它证明分块解法Ⅱ是一个行之有效的算法。
This article is the continuation of the article “An application of the sub-block solution in the calculation of antenna backstructure.” Emphasis is given to the direct solution to the problem of using small machines to solve large problems under the circumstance of small capacity of external memory. Ⅱ. Control parameters can greatly reduce the dependence on external memory. It can even be used in the absence of external memory Continuing with the topic, it is sometimes useful to analyze large structures using the finite element method on small domestic and small aircraft. In this paper, the basic idea of the block solution method is reviewed, two kinds of block solution methods are compared, and the block diagram of the block solution method II is given. The appendix at the end of the text provides the ALGOL-60 language block decomposition method Ⅱ process. The article gives the results of DJS-21 test program, which is based on the analysis method of beam girder backspan of ring girder antenna, which is proved by the block method II. It shows that the block method II is an effective algorithm.
