摘 要: 应用U变换法和有限差分法,研究了简支梁的屈曲问题,求得了临界荷载的解析解和误差项系数的精确值,并对两种不同的差分格式的收敛速度进行了比较. The U-transformation and finite difference method are used in the study of (static,) buckling and dynamical analysis of structures. A buckling analysis is presented for a (simply) supported beam. The exact analytical solutions of buckling loads and the coefficients of the main error are obtained.
