| 摘 要： | 应用传递函数方法求解圆弧曲梁,将复杂的曲梁分成若干一维子系统,轴力作为子系统的参数,通过引入状态变量,将曲梁的控制方程及边界条件改写成状态空间形式,再借鉴有限元的拼接方法,得到梁的变形解.文中的数值算例显示了此方法的可行性.

| Abstract: | The curved-beam of which axes is an arc is very prevalent in projects. But the calculation of its deformation is complex.Distributed transfer function method for arc curved-beam is presented in this paper.In this method,a complex curved-beam is divided into one-dimensional subsystems,and axial force is regarded as a parameter of the subsystem.With the introduction of state vectors,the control equations and the boundary conditions of curved-beam are transformed to state space form.Then using the method of FEM to assemble subsystems,the result of deformation of curved-beam is obtained.Numerical example in this paper shows the efficiency of the method. |
