摘要
起重臂架是浮吊施工作业的重要执行机构,其设计优劣对于整个结构的安全性和可靠性具有重要意义。针对万吨级浮吊研发项目中12 000 t起吊质量对臂架结构的重载荷要求,利用有限元分析了支管连接部的结构强度,从增大支管直径、壁厚,添加臂架箱型梁内部隔板等3个方面来优化结构设计,最终得到了既满足强度要求,又尽量减少臂架增重的设计方案。
Crane arm is an import actuating mechanism of floating crane, which determines whole safety, and reliability of the equipment. In order to meet high load requirement of 12000t floating crane in ten thousand class floating crane developing project, the finite element method （FEM） is applied to analyze the structure strength of boom joint on crane arm. Structure design is optimized by increasing boom diameter and thickness, adding support separates in boom box girder respectively. Finally, optimized scheme is achieved with the consideration of both meeting strength requirement and controlling boom weight.
