摘要:
本文提出了用五次多项式作为回归方程的模式,运用逐步回归的方法,从光弹实验数据中求出回归方程,进而计算出截面上各分点处的等色线(或等倾线)的值,为实现光弹性实验数据完全自动化整理提供保证,并为其他有关实验数据自动整理开辟了道路。文中简述了所应用的逐步回归中的公式和步骤;概述了为在计算机上实现自动处理所作的一些工作;并介绍了平面光弹性剪应力差法实验数据自动整理的源程序框图。
Abstract:
In this paper the author uses a fifth order polynomial as a mode of a regressive equation which has been obtained from the data of photoelastic experiments by means of the step-by-step regression, and succecdes in calculating the fringe orders and the parameters of isoclinic lines at arbitrary points of the model section. This provides us with a method of fully automatic data-processing in photoelastic experiments and also in other proper investigations. Here a brief description of the regressive equation and the process of regression is given. The flow chart and the program for automatic data-processing by using the method of stress differences in two-dimensional photoelastic experiments are presented, resulting in realization of proposed automatic data-pocessing.
