冲击载荷下防甩件动态响应试验和数值分析研究
Test and numerical simulation analysis of the anti-whipping restraint subjected to impact loads
摘要
Abstract
In order to study the anti-whipping performance of anti-whipping restraints,experimental research and numerical analysis were conducted on the dynamic response of anti-whipping restraints under axial impact loads,and the strain rate effect of anti-whipping restraint materials under different impact load conditions in the numerical analysis method was considered.The research results show that the anti-whipping restraints selected in this study have good energy absorption and anti-whipping limiting ability.In addition,the numerical analysis results used in this study are in good agreement with the dynamic response results of axial impact tests with a peak acceleration deviation of less than 10%,which fully verifies the effectiveness of the numerical analysis method of Cowper-Symonds viscoelastic material constitutive model that considers material strain rate effects in numerical analysis of honeycomb sleeve shaped anti-whipping restraints.This method provides a more accurate and faster analysis method for the design of anti-whipping performance of anti-whipping restraints and can effectively reduce design analysis costs.关键词
