关于圆轴含有弯弯组合的合成弯矩图形状的讨论

ANALYSIS OF COMPOSITE BENDING MOMENT DIRGRAMS UNDER BENDING AND BENDING DEFORMATON FOR ROUND SHAFT

本文结合弯弯扭组合变形的例题,利用相关数学知识,证明了圆轴含有弯弯组合的合成弯矩图如果出现曲线,则该曲线必是(上)凹的.

Based on the interrelated mathematics knowledge, through an example, the curves forms of composite bending moment diagrams are analyzed in this paper. The discussion is centered on whether the curves' form is concave . It is proved that the curves of composite bending moment diagrams must be concave curves under bending and bending deformation for round shaft.
