用ANSYS软件建立吊斗铲三角结构塔架实体模型,在吊臂不同安装倾角下,对三角架的结构强度和刚度进行有限元分析,得到其应力、变形分布情况。据此校核三角架的稳定性,并给出应力较大部位的改进建议。
The solid model of the tower crane triangle structure was established by ANSYS software. The structure strength and stiffness of the tripod were analyzed by finite element method under different installation inclination angles of the boom. The stress and deformation distribution were obtained. Based on this, the stability of the tripod was checked and suggestions for improving the larger part of the stress were given.
