人工软骨仿生材料缓震吸能性能的实验与数值研究
Experimental and Numerical Study on Cushioning and Energy Absorption Properties of Artificial Cartilage Biomimetic Material
摘要
Abstract
In order to study the impact protection mode of 7075/T651 aluminum alloy(rocket body material),the cushioning and energy absorption properties of artificial cartilage Biomimetic material(ACF material),two new foam materials with different densities,were studied by combining experiment and numerical simulation.The material compression tests at different rates were carried out to obtain the mechanical properties of the material at different strain rates.The protective performance of ACF material against aluminum alloy was studied through low-speed impact experiments.The impact stress,model energy change and displacement of aluminum alloy were analyzed based on the numerical model of low-speed impact.The experimental and numerical simulation studies show that the mechanical properties of ACF material have strain rate effect and are related to density.The foam material significantly reduce the impact stress on the protected object and has good cushioning and energy absorption.In addition,it can be used as an excellent arrow body protection material because of its low density and good flexibility.关键词
