摘要：以圆锥管螺纹为研究对象,在弹性力学的基础上,结合组合厚壁圆筒理论,对圆锥管螺纹齿面过盈配合进行了理论分析,建立了一种新的解析模型,得到了圆锥管螺纹接触齿面上的径向接触应力和变形公式。并以API-P110SΦ88.9 mm圆锥套管螺纹为例,对螺纹牙的径向变形和径向应力进行了实例计算和有限元分析,通过将解析计算结果与有限元计算结果进行比较分析,证明所建立的计算模型具有较好的准确性,为精确计算圆锥管螺纹过盈联接的应力、变形提供了一种新的方法。
Based on elasticity,the radial stress distribution and deformation on the teeth were studied for the conic thread connection with interference by thick-cylinder theory,and a new calculation model was established through the theoretical analysis.A calculating example for API-P110S Φ 88.9 mm oil tube indicates that this method is practicable.Compared with the result obtained by the finite element analysis,the model estabilished has high accuracy.The model deprived in this paper offers a new way for the calculation of stress and deformation of the conic thread connection.
