谈结构力学中快速画弯矩图的窍门

Tips for rapidly drawing bend moment diagram in structure mechanics

以如何快速画出杆件弯矩图为例,详细阐述了结构力学中解题时的某些可循规律,指出快速画弯矩图是结构力学学习中一个重难点,掌握快速画弯矩图的窍门不仅可以快速准确地画出结构的弯矩图,加快解题速度,更可以激发学生学习结构力学的乐趣,使得学习事半功倍。

Taking how to rapidly draw bending moment diagram as an example,the paper illustrates structural mechanics problems solving law. And then,it points out that：rapidly drawing bending moment diagram is a critical point in structural mechanics,grasping techniques of rapidly drawing bending moment diagram can not only draw bending moment diagram as fast as possible,but also can speed up problems solving,and to induce students’learning interesting.
