摘要
本文根据力矩—面积法、叠加原理及阶梯函数,建立阶梯式悬臂梁的挠度公式,用相对挠度表示的转角以及与挠度的联通方程,推导出阶梯式连续梁的三弯矩方程,并借助微机计算及绘制其挠曲线。该方法在工程机械中的应用,获得比较满意的效果。
The deflection calculation formula was set up according to the moment—area method, piling principle and ladder function. After the linking—up equation was completed between the deflection, the relative deflection and the bending angular which is expressed in relative deflection , the three—bend—moment—eqution was deduced, and the calcualating and drawing of the deflection curve were accomplished with a microcomputer. This method can be satisfiedly used in engineering machines calculation.
