本文讨论了由圆柱形和圆锥形段组成的变截面筒支粱在扭矩、集中力、集中力偶和均布载荷等外载作用下的计算机处理问题.按梁的结构和受载情况对梁进行分段,建立了梁的扭矩、剪力、弯矩和变形的分段计算模型;多支承梁按力法建立补充方程,将中间支承反力作为外力实现静定化.此方法简单易行,计算量小,适合于计算机处理.用 BASICA 编制的程序,通用性强.
This paper discusses the computer processing problems of varying cross-section tube supports consisting of cylindrical and conical sections under external loads such as torque, concentrated forces, concentrated couples, and uniform loads. The beams are subjected to beam structure and loading conditions. Segmented, a segmented calculation model for the torque, shear force, bending moment and deformation of the beam was established; a multi-support beam was built by a force method to complement the equation, and the intermediate bearing reaction force was used as an external force to achieve static determination. This method is simple and easy. Small amount of calculation, suitable for computer processing. The program compiled with BASICA has strong universality.
