摘要
吊臂是起重机的最主要承载构件之一,吊臂的分析研究对于起重机的结构优化起着重要作用。以研制的1 000 t大型海工绕桩式起重机吊臂为研究对象,建立了数学模型和三维实体模型,优化了吊臂的设计结构。通过软件Ansys Workbench对吊臂结构的全伸臂工况进行有限元分析,得到相应的应力云图,验证了优化后的吊臂满足使用强度要求。
The boom is one of the most important bearing components of the crane. Through the boom hoisting, the crane can achieve large height and large scale operation. The analysis and research of the boom plays an important role in the structural optimization of the crane. Taking 1 000 t large marine crane boom as the main research object, the theoretical mathematical model was constructed, the three-dimensional solid model was established based on Auto CAD software. The finite element analysis of the full extension arm condition of the boom structure was carried out with the help of the software Ansys Workbench, and the corresponding stress and displacement cloud pictures are obtained, and the static analysis results and the foundation satisfying its strength were obtained. On the basis of the optimization goal of minimizing the mass, the structure of the boom was optimized, which provided the necessary reference for the improvement and optimization of the structure.
