| 摘要: |
| 以粘弹理论为基础,采用Volterra算子,建立了复合固体推进剂松弛模量和蠕变柔量之间的相互转换关系。结果表明:由松弛模量计算蠕变柔量的理论值与实验值吻合;该转换表达式避免了数值积分法求解蠕变柔量值产生舍入误差和采用拉氏变换的繁琐计算。研究方法可以用于固体推进剂其它力学参数的转换计算,如体积松弛模量和体积蠕变柔量之间的转换计算。 |

| Abstract: |
| Based on viscoelastic theory, conversion relations between relaxation modulus and creep compliance of composite solid propellant was established. The results obtained from relaxation modulus show good agreement with experimental data of creep compliance. This expression avoids rounding error brought by numerical integral method and complex calculation of Laplace transforms. This method can be used in conversion of other mechanics parameters. |
