摘　　要：建立了等截面纵横弯曲梁的分布传递函数求解模型。这种模型可以适应复杂的边界条件和外力情况,表达公式形式简单规范,便于计算机编程处理。对于复杂系统,根据外力和约束的情况,将其分成多个子系统,并依照分布传递函数方法分别对每个子系统进行处理,借助有限元方法,建立整个系统的平衡方程,最后得出问题的解。The solution model of distributed transfer function method of uniformed vertical and horizontal bending beam is figured out. The model is applicable to complicate boundary conditions and external forces. The shape of formula is simple and standard. It is easy to deal with computer. The complicate system is divided into subsystems according to the outside forces and constraints. Using the distributed transfer function method and FEM, the equilibrium equations can be solved.
