摘要:
抽油机减重在工程设计中具有重要的经济意义,直接关系到运营成本和能效提升,针对12-8CYJ-00型抽油机的支座结构进行尺寸优化,以实现轻量化设计。首先,利用ABAQUS软件平台对整体结构进行强度分析,以获取不同工况下支座的载荷情况,并选取对应最大Mises应力的工况作为优化边界条件。结合Python编程语言与ABAQUS的数据交互能力,构建Python-ABAQUS优化框架,并通过灵敏度分析实现参数的自动寻优。建立参数化模型并进行有限元计算,明确了结构参数与最大Mises应力之间的函数关系,经过多次优化迭代,最终实现支座结构的轻量化设计。结果表明:支座结构重量减少了12.44%,尽管最大Mises应力增加了10.01%,但仍满足结构强度要求。这一优化设计不仅降低了材料使用成本,为抽油机的高效运行奠定基础,也为后续相关研究提供了有价值的参考,展示了未来在其他机型减重设计中的应用潜力。
Abstract:
Reducing the weight of the oil pumping rig is of economic significance because it is directly related to cost and energy efficiency. We carried out dimensional optimization for the support structure of the 12-8CYJ-00 oil pumping rig to achieve lightweight design. First, we utilized the ABAQUS software platform to conduct strength analysis on this structure, so as to obtain its load situation under different working conditions, and took the working condition corresponding to the maximum Mises stress as the optimization boundary condition. Then, a Python programming language was used to interact with the ABAQUS data, and a Python-ABAQUS optimization framework was built. The parameters were automatically optimized through sensitivity analysis. A parameterized model was established and finite-element calculation was carried out to clarify the functional relationship between the structural parameters and the maximum Mises stress. After several optimization iterations, the lightweight design of the support structure was finally achieved. The results showed that the weight of this support structure is reduced by 12.44%, and although the maximum Mises stress has increased by 10.01%, it still meets its structural strength requirements. This optimized design not only reduces the material cost and ensures the efficiency of the oil pumping rig, but also demonstrates its application potential in other pumping unit models, providing a valuable reference for future related researches.
