针对系列化塔机起重臂的结构特点,研究程序化的方法实现起重臂的参数化有限元建模。采用循环控制程序依次在起重臂各工作幅度位置施加相应的工作载荷,实现对有限元模型进行多载荷步的解算。
Aiming at the structural characteristics of the boom of the tower crane, the parametric finite element modeling of the boom is studied by using the programmed method. The cyclic control program is used to apply the corresponding working load to each working range of the jib in order to solve the multi-load step of the finite element model.
