“相当弯矩法”计算梁(轴)变形的电算法

An Eelectrical Calculus Way for Calculating the Deforma tion on of a Beam with Method of Equal Bending Moment

本文应用“相当弯矩法”对各种载荷作用下的变圆截面静定梁的变形(转角和挠度),用 BASIC 通用程序计算,得出小变形情况下的精确解,并绘制出大致的挠度曲线图.确定梁(轴)变形是工程中广泛存在的问题。建立通用程序既可快速、简便地解决工程实际问题,叉可以使“相当弯矩法”——优化的计算方法得到推广。

In this paper the method of equal bending moment it used to calculate the deformation of statically determinate beam with varying circular cross section and under the action of various kinds of loadings,and a commonly used BASIC program of this method is raised.With this program the accu- rate solution can be gained in the case of small deformation and the defec- tion curve can be roughly drown out. It is a widely existing problem in engineering to determine the defor- mations of beams or axes.Raisng a commonly used BASIC program is very helpful not only in solving practical engineering problem easily and rapidly,but also in spreading the refined calculating metaod of equal bending moment.
