【摘要】 通常情况下材料力学中关于梁弯曲问题的计算过程非常复杂和繁琐,要想通过手算快速、准确地得到理论解是不现实的.该文基于材料力学梁弯曲的叠加原理,对承受多个不同类型载荷作用下变截面梁建立了一种通用力学模型,得出梁任一截面的弯矩方程.通过对弯矩方程的积分,得到梁上任意截面的转角和挠度变形的叠加方程.采用VB技术对材料力学中梁弯曲问题进行计算,开发出一款软件——受多个不同类型载荷作用下的变截面梁弯曲问题力学求解器.通过该软件可实现变截面梁弯曲问题分析,计算过程高效快捷,计算结果准确.更多还原

【Abstract】 The calculating process about the beam bending problems in material mechanics is usually very complicated and boring.it is easy to obtain the theoretical-solutions rapidly and accuratly by hand.A normal mechanical model based on the superimposing theory in material mechanics is established in this paper for non-uniform cross-section beam,which bearing different kinds of multiloads,the bend moment equation.is given.The corner equation and flexure equation,which can be superimposed,are also given by integral way.A software,which was named bearing different kinds of multiloads and non-uniform cross-section beam mechanical solution,was developed by VB technology.The calculation process is of high efficiency and fast,and the results are accurate.更多还原
