摘要
为了研究膨胀式防爬器的吸能特性，对不同厚度膨胀管的材料性能进行分析，研究了不同约束方式对静压仿真稳定段均值力的影响。通过仿真与试验对比，得到2种轮廓加压锥与膨胀管配合关系下的摩擦因数；进行不同应变率下的材料试验，研究了不同硬化模型对膨胀管高速冲击稳定段均值力的影响，并基于SHS硬化模型对不同冲击速度下的稳定段均值力进行分析。研究结果表明：不同厚度的膨胀管材料性能差异明显，不同边界约束方式对静压仿真稳定段均值力改变明显；不同轮廓加压锥与膨胀管配合关系下的摩擦因数不同，稳定段均值力均与摩擦因数呈正相关；采用不同硬化模型仿真得到的高速冲击稳定段均值力基本相同；使用SHS硬化模型仿真得到的不同冲击速度下的稳定段均值力基本相同，仅在碰撞初始时表现出应变率效应；采用1/4简化模型能够在保证计算精度的同时显著提高计算效率。
Abstract
In order to study the energy absorption characteristics of expanding anti-climber
the material performance of expanding pipes with different thicknesses were analyzed. The influence of different restraint methods on the average force value on simulated static pressure section was studied. Through the simulation and comparison of tests
the friction coefficients under the two matching relationships of pressure cones and expansion tube were obtained. Material tests at different strain rates were carried out to study the effects of high-speed impact force on the stable section in different hardening models
and the forces on the stable section at different impact speeds were analyzed based on the SHS hardening model. The results show that the material performance of expansion pipes with different thicknesses varies significantly and different boundary constraints significantly change the static pressure simulation force value. The friction coefficients are different between different pressure cones and expansion pipes
and the value of force increases with the increase of friction coefficient. The average forces on the stable section obtained by high-speed impact are basically the same in different hardening models. The force values of different impact speed on the simulated stable section are basically the same in SHS hardening model
and strain rate effect only shows at the initial stage of the impact. Adopting 1/4 simplified model can significantly improve the calculation efficiency without compromising the calculation accuracy.
