摘要
对泡沫铝缓冲吸能特性的评估方法进行了比较分析 ,明确了吸能效率曲线与理想吸能效率曲线的应用范围 ,为缓冲器的选材与设计提供了依据。同时还对四种密度的泡沫铝在动静态下的缓冲吸能特性进行了评估 ,研究表明 ,泡沫铝是一种优良的吸能材料。
In this paper, the different evaluation methods of the cushioning properties of foam aluminum are compared and analyzed. The application range of the ideal energy absorption efficiency curve and energy absorption efficiency curve are confirmed and they offer the tools of choosing the material for buffer and designing buffer. Under the condition of static and dynamic loading, the energy absorption properties of four kinds foam aluminum with different density are evaluated, which indicate that foam aluminum is a kind of excellent material of energy absorption.
