图乘法求挠曲线方程的研究

A Solution of Deflection Curve Equation with the Method of Graphic Multiplication

在设计桥梁、屋梁等结构时,常常要计算梁的最大挠度,而通过积分求平面弯曲梁的挠曲线方程是比较繁琐的。当集中力、集中力偶或均布载荷作用于平面弯曲梁时,可以用图乘法计算梁的挠曲线方程,从而避开积分过程。

Deflection must be calculated when a bridge or a house is designed.Compared with integral calculation,the method of graphic multiplication works more efficient in case the central force,the concentration coupling or the uniform load function curve beams.
