多吊点结构的设计可以提高大型高处作业吊篮的安全性和稳定性,利用ANSYS Workbench自身建模功能模块建立吊篮简易模型,并且对此模型进行优化设计,寻求内部吊点最优位置。再根据内部吊点最优位置,分析其真实模型危险工况下的力学性能,获取结构整体的应力应变分布规律,同时将静力分析结果与理论设计值进行比较,得出强度和刚度均在设计要求的范围内。最后指出四吊点吊篮为超静定结构简支梁,通过计算分析其吊点受力,得出吊点位置优化设计方案。
The design of multi-hanging point structure can improve the safety and stability of large-scale high-altitude work basket. Using the self-modeling function module of ANSYS Workbench, a simple basket model is established, and the optimal design of this model is optimized to find the optimal position of internal hanging point . According to the optimal position of internal hanging point, the mechanical properties of the real model under dangerous conditions were analyzed, and the stress-strain distribution of the whole structure was obtained. At the same time, the static analysis results were compared with the theoretical design values, Within the design requirements. At last, it is pointed out that the four-suspension point basket is a simply supported beam with statically indeterminate structure. By calculating and analyzing the stress of its suspension point, the optimum design of suspension point position is obtained.
