聚氨酯泡沫塑料吸能特性研究

Study of Engergy-Absorbin Properties of Polyurethane Plastic Foam

本文介绍了利用分离式Hopkinson压杆对聚氨酯泡沫塑料进行的一种高应变率实验 ,给出了聚氨酯泡沫塑料在高应变率下的动态应力 应变曲线 ,对聚氨酯泡沫塑料的动态力学性能及吸能缓冲特性进行了深入的分析。

This article is intended to show you a high strain rate experiment about polyurethane plastic foam by using split Hopkinson pressure bar,and give polyurethane plastic foam's dynamic stress-dynamic strain under the condition of high strain rate.It then analyses deeply the dynamic mechanic properties,energy-absorbing and cushion of polyurethane plastic foam.
