纹管直径变化对端面受力和变形的影响
|
摘要
基于ANSYS有限元分析软件,对金属螺纹管的参数进行模拟.结果表明:预压缩条件下,端面变形、预压缩和外压组合条件下,随着轴径的增加,端面呈现左低右高的趋势;随着轴径的增大,端面垂直方向的压力右端大于左端,轴径越大间隙越大;在常温和高温情况下,端面变形呈现左高右低的规律,接触对的最大应力出现在竖直接触面的下部和水平接触面的内部.
Based on ANSYS finite element analysis software,the parameters of metal threaded pipe are simulated.The results show that under the condition of end face deformation under pre-compression condition and the combination of pre-compression and external pressure,the end face exhibits a trend of left low and right height with the increase of shaft diameter;with the increase of shaft diameter,the pressure of the end face perpendicular direction The right end is larger than the left end,and the larger the shaft diameter is,the larger the gap is;at normal temperature and high temperature,the deformation of the end surface exhibits a law of left high and low right,and the maximum stress of the contact pair appears in the lower part of the vertical contact surface and the inside of the horizontal contact surface.
