| 摘 要： | 工程中的梁，在线性分布载荷作用下，可以用图乘法求任一载面的线位移和角位移和角位但是对于弯矩图三次抛物线的荷载，根据有关教材所给的特性求解，很麻烦、甚至会产生错误，本文采用叠加原理，分部载荷法及图乘法的原理，使能简捷而准确的求解。

| Abstract: | The displacement of any cross section of a beam under linear load, in engineering, can be calculated by using diagram multiplication However,there will be an error in the result if the method depends on the geometrical characteristics of the third power parabola given by some textbooks By applying laminating principle, section load method and diagram multiplication, this paper presents an simple and accurate way to slove the problem |
