摘要
文中利用ANSYS研究了多层波纹管的摩擦系数对波纹管轴向刚度的影响,同时确定了多层波纹管的单层等效厚度值,并将单层波纹管模型所得轴线刚度值与实际测量结果进行比对.计算结果表明:摩擦系数设置为0.15 时,轴向刚度值多层波纹管仿真计算结果所得的误差最小,为 5.6%.单层等效厚度法所得轴向刚度误差为4.4%.说明单层等效厚度法计算结果的误差更小.文中研究证明了单层等效厚度法的可行性,也为获得波纹管轴向刚度值提供参考.
Abstract
The effect of the friction coefficient of multilayer corrugated pipes on their axial stiffness was studied in ANSYS.At the same time,the equivalent thickness value of a single layer of the multilayer corrugated pipe was determined,and the axial stiffness values obtained from the single-layer corrugated pipe model were compared with actual measurement results.The calcu-lation results indicate that when the friction coefficient is set to 0.15,the error in the axial stiffness value obtained from the multi-layer corrugated pipe simulation is minimized at 5.6%.The axial stiffness error using the single-layer equivalent thickness method is 4.4%.This demonstrates that the error in the results obtained by the single-layer equivalent thickness method is smaller.This study confirms the feasibility of the single-layer equivalent thickness method and provides reference for obtaining the axial stiffness value of corrugated pipes.
