基于Ansys的多层波纹管疲劳特性分析研究
Analysis study on fatigue characteristics of multi-layer bellows based on Ansys
摘要
Abstract
To address the unclear influencing factors and unclear patterns of fatigue life of multi-layer bellows,the finite element method was used to analyze the stress distribution characteristics of a 9-layer bellows,and the influence laws of friction coefficient(0.05～0.30)and interlayer clearance(0.05～0.30 mm)on the fatigue life of the 9-layer bellows were investigated.The results show that under the combined action of external pressure and tensile load,the effect of interlayer friction coefficient variation on fatigue life is relatively limited,while the effect of interlayer clearance is extremely significant.When the clearance increases from 0.05 mm to 0.30 mm,the fatigue life drops sharply from 1 184 cycles to 955 cycles,a reduction of 19%.Through experimental testing,the error between the simulation-predicted fatigue life of 1 163 cycles and the experimental fatigue life of 1 081 cycles is 7%,fully demonstrating the accuracy of the model.This study provides important theoretical basis and technical support for the design and manufacture of multi-layer bellows,and has significant engineering application value for improving the reliability application of bellows in thermal engineering,petrochemical,and other fields.关键词
