Research on Creep Characteristics of the Double-base Solid Propellant

摘要：

　　The uniaxial tensile creep tests of the double-base solid propellant specimens were carried out at 45℃ under five different stress levels.The viscoelastic models such as three parameters solid model,Burgers model,generalized Kelvin model,five parameters solid model and exponential model were adopted.The computation equation that can describe the strain rate of the second creep stages of the double-base solid propellant under different applied stress levels was founded on the basis of these creep tests,and the adaptability of the five models on creep characteristics of the double-base solid propellant were studied.The study results shows that the five models can show good agreement with second creep course of propellant under different applied stress levels,but the generalized Kelvin model may have optimal characterize creep curve of the double-base solid propellant.
