摘要
介绍了用分离式Ｈｏｐｋｉｎｓｏｎ压杆对硬质聚氨酯泡沫塑料（ＲＰＵＦ）进行的一种高应变率实验，第一次完整地给出了ＲＰＵＦ在１０￣３ｓ￣（－１）高应变率下的动态应力应变曲线，并对ＲＰＵＦ的动态力学性能及其吸能缓冲机理作了简单的分析。
In this paper,the experimental results of rigid polyurethane foam(RPUF) under high strain-rate by Split Hopkinson Pressure Bar are presented. The dynamic stress-strain curves of RPUF at about 10￣3 s￣(-1) strain rate have been given for the first time,and the dynamic mechanical behaviour as well as the mechanism of energy absorption and cushioning action are analyzed briefly.
