从函数图像绘制角度统一看四种内力图绘制
|
摘要
材料力学中内力图的绘制贯穿材料力学强度学习的整个过程,也是工程中结构分析重要的一环,因此,掌握好内力图的绘制,对于培养学生的工程分析能力至关重要。本文从数学函数图像绘制的角度,揭示了内力图绘制的本质,提出了四种内力图绘制的统一思想并小结了若干绘图技巧,以使学生能快速准确绘制内力图。
The drawing of internal force diagrams in material mechanics runs through the entire process of material mechanical strength learning,and is also an important part of the structural analysis in the project.Therefore,mastering the drawing of internal force diagrams is very important for cultivating students' engineering analysis ability.This article reveals the essence of internal force diagram drawing from the perspective of mathematical function image drawing,proposes unified ideas of four internal force diagram drawing,and summarizes some drawing techniques,so that students can draw internal force diagrams quickly and accurately.
