摘要

摘要: 为了研究HTPB推进剂在冲击载荷下的能量耗散规律，结合分离式霍普金森压杆(SHPB)搭建了红外测温系统。该系统响应速度快，可同步获取冲击实验中HTPB推进剂表面的温度变化。结果表明，HTPB推进剂受载后表现出黏-超弹特性，并且在高速变形中试件经历了温度的显著升高。在黏-超弹性本构模型的基础上引入温度项，考虑了热软化效应，更加准确地描述了HTPB推进剂在高应变率变形下的热力学响应，可对复合固体推进剂在冲击载荷下的热力耦合分析提供参考。

Abstract: In this study, using a split Hopkinson pressure bar (SHPB), we assembled a fast-responding infrared temperature measurement system, capable of simultaneously obtaining the superficial temperature change of the HTPB propellant in impact experiments, to investigate the energy dissipation pattern of HTPB propellant under impact loading. The results show that the HTPB propellant exhibited visco-hyper elastic properties, and experienced significant temperature rise in high speed deformation. Based on the visco-hyper elastic constitutive model, we also introduced a heat softening function to more accurately describe the thermodynamic response of the HTPB propellant at high strain rates. Our results provide support for the analysis of thermo mechanical coupling of the solid composite propellant under impact loading.
