基于MATLAB梁受力分析工具箱的材料力学教学方法研究

Research on Material Mechanics Teaching Method Based on MATLAB Beam Stress Analysis Toolbox

梁构件的受力分析是材料力学教学当中的重要内容,完整并透彻掌握不同类型梁构件在不同外力、支撑方式下的剪力、弯矩分布是后续梁截面应力、挠度以及强度等核心教学内容的基础。现阶段梁剪力、弯矩的教学主要采用固定例题讲解的方式,缺乏互动性及多样性,制约了材料力学的教学效果。采用MATLAB梁受力分析工具箱实时演示不同截面形状、尺寸梁构件在不同支撑条件、载荷下的剪力弯矩分布及变化,极大地拓宽了授课方式的多样性与交互性,提高了材料力学的教学效率与效果,促进了学生学习的积极性,满足了学生课后自主探索的需求,值得推广使用。

The force analysis of beam components is an important content in the teaching of material mechanics.A complete and thorough understanding of the shear force and bending moment distribution of different types of beam components under different external forces and support methods is the basis for subsequent core teaching content such as beam section stress,deflection,and strength calibration.At present,the teaching of beam shear force and bending moment mainly adopts a fixed example explanation method,lacking interactivity and diversity,which restricts the teaching effect of material mechanics.The MATLAB beam force analysis toolbox is used to demonstrate in real-time the distribution and changes of shear moment of beam components with different cross-sectional shapes and sizes under different support conditions and loads,greatly expanding the diversity and interactivity of teaching methods,improving the teaching efficiency and effectiveness of material mechanics,promoting students'enthusiasm for learning,and meeting their needs for independent exploration after class.It is worth promoting and using.
