摘要

采用精细传递矩阵法,根据压杆微弯平衡状态下的微分方程,建立了在不同荷载作用下压弯杆弹性弯曲分析的精细传递矩阵式,并运用精细传递矩阵法对两端铰支的压弯杆进行了内力计算.算例表明,该方法正确有效.
Based on the slightly bend differential equation of a compression bar,a precise transfer matrix format for the elastic bending analysis of the compressive-bending bar under different loads is derived through the precise transfer matrix method.Internal forces of the compressive-bending bar with different boundary constraints are calculated by the mothod.Examples show that the method is right and effective.
