摘要
梁的弯曲变形是材料力学的核心内容之一。本文基于梁的弯曲变形理论,以悬臂梁的弯曲变形为基础,给出了一种求解梁弯曲变形的“特殊叠加法”,该方法对于计算简支梁、外伸梁以及变刚度梁的变形问题尤为方便和有效。
The bending deformation is one of the core contents of mechanics of materiails. Based on the theory of bending deformation of beams, and the bending deformation of cantilevers, a “special superposition method”for solving the bending deformation of beams is proposed. This method is particularly convenient and effective for calculating the deformation of simply supported beams, overhanging beams and variable stiffness beams.
