摘要: |
采用非接触测量体积模量系统,测出了复合固体推进剂在不同温度下的体积松驰模量和体积蠕变柔量,并依据时间-温度等效原理迭加拟合求得了体积模量主曲线和温度移动因子的数学表达式,其结果可为发动机药柱结构完整性分析提供依据。 |

Abstract: |
The bulk relaxation modulus and bulk creep compliance of solid propellant at different temperatures are measured by a self-designed contactless measurement system, and the corresponding mathematical expressions of the master cure for bulk modulus are also given. The results are of practical significance to motor grains in structural integrity analysis. |
