摘要
借助数学分析,研究了弯曲位移与弯曲变形的关系,指出描述弯曲变形的基本量是曲率.并通过实例分析,分别用弯曲位移和曲率描述弯曲变形的程度,其结果是不一致的,证明弯曲位移不能完全反映弯曲变形的程度,指出单纯用弯曲位移度量弯曲变形具有不完整性.最后分析了弯曲位移不能完全反映弯曲变形程度的原因,并指出了根据弯曲位移建立刚度条件的工程背景.
Firstly, the relation between the bending displacement and the bending deformation is studied with the help of mathematical analysis . We show that the curvature is the fundamental quantity in measuring the bending deformation. Secondly,using the bending displacement and curvature separatly,we analyze some bending deformation by means of the bending displacement and the curvature,respectively.The results are out of accord with each other.This proves that the bending displacement does not express the bending deformation completely. Last, the reason is given.
