| 摘 要： | 为得到钢丝缠绕式重型液压油缸在预应力状态和工作状态的应力和变形分布情况,建立了解析计算模型和有限元数值模型并进行了模拟计算和分析。结果表明:缸体的径向变形是轴向位置的函数,半径方向的应力是径向位置的函数。基于有限元数值模拟结果与解析计算结果在数值和变化趋势上均趋于一致,充分地证明了建模的正确性。基于钢丝缠绕重型油缸的整体有限元分析方法大大地降低了设计计算难度,提高计算结果的准确性,为结构的进一步优化和设计改进提供理论依据。

| Abstract: | In order to get the distribution of stress and deformation for the steel wire winding heavy hydraulic cylinder under prestressed state and working state. The analytical model and the finite element numerical model are established in the research, and the simulation and analysis are carried out. The results show that the radial deformation is the function of axial position and radial stress is the function of radial position. The value and trend of finite element analysis method and analytical method are consistent, This can prove that the model of hydraulic cylinder is right in ANSYS. The integrated finite element analysis method based on steel wire winding heavy hydraulic cylinder not only greatly reduces the difficulty of computation and analysis, but also improves the accuracy of calculated result. This method provides a theoretical basis for further structural optimization and design improvement. |
