海洋钻修井机绞车滚筒有限元分析及优化设计

摘要

In the light of the lightweight requirements of offshore drilling and workover rig winch, the paper applies the finite element analysis to the winch drum body and drum axle with Ansys software, and acquires the maximum displacement and stress distribution. The results show that the strength and stiffness meet the requirements under the maximum hook load condition. Via the optimization applied to the structural dimensions of the drum by Ansys software, the paper gets optimal drum size required by the working of the winch, and the results show that the optimized structure meets the strength and stiffness requirements. The drum structure optimization design introduced in the paper can be used to guide the actual production.%针对海洋钻修井机绞车轻量化的要求,利用Ansys软件对某海洋钻修井机滚简体和滚筒轴进行了有限元分析,得到了最大位移及应力分布.结果表明,最大钩载工况下其强度和刚度满足要求.通过Ansys软件对滚筒结构尺寸进行优化,得到符合绞车工作要求的最优的滚筒尺寸,结果表明优化的结构也满足强度及刚度要求.文中提出的滚筒结构优化方案可用于指导生产实际.
