| 摘要: |
| 以粘弹理论为基础，采用拉氏逆变换和数值积分的方法，推导出由拉伸松弛模量Ｅ（ｔ）、粘弹泊松比ｖ（ｔ）计算固体推进剂体积松弛模量Ｋ（ｔ）的计算公式和数值解法。计算结果表明，由该方法计算的Ｋ（ｔ）值和实验得到的Ｋ（ｔ）值一致，且该方法简单、实用、方便、精度高。 |

| Abstract: |
| n base of viscoelastic theory and using inversion of the Laplace transform and numerical calculation method,a formation and a numerical solution for bulk relaxation modulus K(t) from stress tension modulus E(t) and viscoclastic poisson ratio v(t) are obtained.The calculation results show good agreement with experimental data K(t).The method is very simple and accurate. |
