摘要
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。
Minute bulk deformations in samples have been measured with accuracy under different pressure loadings. Experimental curves of bulk deformation versus pressure as well as the bulk modulus, initial void content for two solid propellants have been obtained through analysis and subsequent processing. Creep curves of one solid propellant under constant pressure have also been obtained. The paper will be useful to structural integrity analysis of grains and to a study of the service life of solid propellants.
