基于CABLE建模的大型塔结构吊装过程动力学模拟

Dynamics Simulation of Large Tower Structure Lifting Process Based on CABLE Modeling

通过在CATIA软件上引入CABLE软件,建立了柔性体钢丝绳的三维模型。在对钢丝绳的物理参数进行定义后,在运动工作台上建立钢丝绳的动力学分析模型。进一步将吊车、塔、地面等模型完整装配,在运动工作台上进行整体模拟计算。最终获得被吊装结构的轨迹曲线、动力学响应、结构的偏心、翻转等;以及与周围物体的干涉情况。

Three-dimensional model of the flexible steel wire rope was established by using CABLE software in CATIA software. After defining the physical parameters of the steel wire rope, the dynamics analysis model of wire rope was established in motion workbench. Further fully model was assembled and simulated including cranes, tower, ground in motion workbench. Finally, hoisting structure of the trajectory curve, dynamic response, eccentric structure, flipping, etc. are obtained, as well as interference with the surrounding objects.
