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）、静态粘弹泊松比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）值与实验得到的K（t）值一致，且该方法简单，实用，方便，精度高。
On the basis of viscoelastic theory,inversion of Laplace transform and numerical calculation is applied in the calculation of bulk relaxation modulus K(t) for solid propellants through the tension relaxation modulus E(t) and viscoelastic poisson ratio v(t).Computational results show that the calculated results K(t) are in good agreement with experimental data and that the method is very simple and accurate.
