| 摘要: |
| 根据一个有效的非线性粘弹模型，导出复合固体推进剂微分形式本构方程和应变速率关系式。分析表明点火瞬态过程中压强与推进剂应变、升压速率与推进剂应变速率之间呈线性关系，线性系数均为推进剂初始模量。 |

| Abstract: |
| Based on an effective nonlinear viscoelastic model, the differential constitutive equation and strain-rate equation of solid composite propellants are induced.Pressure/strain and pressurization rate/strain rate are linear correlation during the ignition transient.And the coefficient is the initial modulus of composite solid propellants. |
| Keywords: nonlinear viscoelasticity ignition transient strain rate |
