通过精确实测不同内压载荷条件下的试件微小体积形变,经过分析处理给出了两种固体推进剂的体积形变随压力变化的实验曲线、体积模量和初始气孔率及一种推进剂的定压蠕变曲线及其结果。该技术和结果对装药结构完整性分析及推进剂储存寿命的研究有重要意义。 By means of accurately measuring the small volume deformation of specimens under different internal pressure loads, experimental curves of volume deformation and pressure variation of two solid propellants were obtained through analysis and treatment. The bulk modulus and initial porosity were compared with that of a propellant Constant pressure creep curve and its result. The technology and results are of great significance to the analysis of charge structure integrity and propellant storage life.
