摘要
利用有限元软件ANSYS建立了90°XGQT01-76.1弯头三维实体参数化有限元模型。通过对弯头实体模型的强度分析得出了弯头在受载时的应力分布情况,根据应力分布状况得出弯头易发生破坏的位置及破坏形式,在这些位置应进行局部加固或避免生产过程中的局部减薄现象。由弯头强度分析得出其最大等效应力远小于材料屈服值,利用参数化模型减小弯头壁厚并对其进行应力分析得出了弯头壁厚的最优值所在区间。
A three-dimensional solid parametric finite element model of 90°XGQT01-76.1 elbow is established by using the finite element software ANSYS. The stress distribution of elbow under load is obtained through the strength analysis of the solid model, which derived the failure position and the failure-prone form of elbow, partial reinforcement should be applied or local wall thinning phenomenon should be avoided during production in these positions. According to the results of strength analysis of the elbow, the maximum equivalent stress is far less than the material yield value, elbow wall thickness is reduced by using the parametric model and where the optimal value range is obtained through elbow stress analysis.
