结构计算中采用电子计算机以后,使得大量繁杂的计算工作都可由计算机来完成,计算所得的数据也可以由打印机输出。然而结构计算时输入数据正确与否的检查以及输出数据的整理仍然是一项繁琐而冗长的工作,特别是要将数据绘制成图形曲线,如果靠人工一点一点地画出来再用曲线板连起来,这不但耗费人力和时间,而且图的质量也难以保证。这样,用计算机来画图就显得非常必要。微型计算机的广泛采用,点阵打印机作为微机的输出设备的采用,使计算机画图技术得到很快发展,除了使用专门配置的卷筒式或平板式绘图仪画图以外,还可以在屏幕上显示图形,并用普遍的点阵打印机把图形打印出来。本文简述VICTOR—9000微机的绘图功能,着重介绍有限单元法结构绘图程序及功能。这种人机对话式的绘图程序使用方便有效,普遍适用于各类微机的绘图程序编制。
Structural calculations using electronic computers, making a lot of complicated calculations can be done by the computer, the calculated data can also be output by the printer. However, it is still a tedious and tedious task to inspect the input data correctly and organize the output data in the structural calculation. In particular, the data should be drawn into a graphical curve. If the data is drawn manually and then the curve plate This not only consumes manpower and time, but also the quality of the picture can not be guaranteed. In this way, it is very necessary to draw a picture with a computer. The widespread adoption of micro-computer, dot matrix printer as the output device of the computer, the computer drawing technology has been developed rapidly, in addition to the use of specially configured reel or flat plotter drawing, you can also display graphics on the screen, And with a common dot matrix printer to print graphics. This article briefly describes VICTOR-9000 computer graphics capabilities, focusing on the finite element method structure drawing programs and functions. This man-machine interactive graphical drawing program is easy to use and effective, generally applicable to all kinds of computer drawing program.
