摘要
利用有限元结构分析ANSYS软件,对重型燃气轮机整机吊具进行了强度和刚度计算,考虑该吊具属单件生产的、需反复使用的随机设备,确定采取能兼顾完成单吊裸机和吊装整机带底座两项任务的结构形式.采用混合建模方法,求得了吊具的最大应力和最大位移,对结构几何形状发生突然改变引起的应力集中进行了分析,对加强肋板的作用进行了探讨.通过计算确定了设计的最佳方案,可以作为设计吊具的施工详细图纸的依据.
Based on the element analysis ANSYS program, this paper analyzes the strength and stiffness for the bearing system of heavy-duty Gas turbine. The bearing system is a single equipment accompanied with machine. It is used repeatedly. It could both hang the bare machine and the complete machine with base. Considering this, the structure form of bearing system was determined. Using mixed modeling method, the maximum stress and displacement of the beating system were calculated. The stress centralization of the geometry structure and the effect of the crescent costal board are researched. In virtue of reduplicative calculations, we confirm the optimum design as the shop drawing of the beating system.
