摘要
利用弯矩和梁挠曲线曲率的数学关系及梁本身的变形协调关系,研究了一种快速绘制梁近似挠曲线的新方法。该方法简单易懂,几何意义直观,有利于学生和工程人员快速预测梁的变形,从而为刚度计算提供更全面的依据。
Using the compatible relationship between the bending moment and curvature of beam＇s deflection curve,this paper studies a new method for fast plotting beam＇s approximate deflection curve,which is simple and understandable,has intuitive geometric meaning,is helpful for the students and engineers to predict the beam deformation rapidly,and thus provides more complete basis for beam＇s rigidity calculation.
