摘　　要：为研究悬挂式单轨轨道梁的加劲肋对其整体挠度的影响,建立了静活载作用下超静定变截面梁的力学模型,以模拟其变刚度条件下的弯曲变形,并推导出轨道梁任意截面的转角和弯曲挠度变形的一般方程。应用Matlab软件编程实现了梁最大挠度的计算机求解,并根据求解结果对悬挂式单轨轨道梁进行了初步的结构优化设计探讨。To study the impact of stiffeners of suspended monorail track beam over the overall deflection,a mechanical model of hyper-static tapered beams under static and live load is established to simulate the bending deformation of variable stiffness,from which the general equation of corner and bending deflection of arbitrary cross-section of the track beam is derived.Then,software Matlab is used to achieve the numerical solution of the maximum deflection of the beam,and the result is applied in an optimum design of the suspended monorail transit structure.
