摘　　要：为研究自然条件下HTPB推进剂最大延伸率变化和寿命评估的模型,基于定应变下高温加速老化对推进剂延伸率的影响,考虑力-热耦合作用,综合线性和指数模型的特点,建立了二元回归模型。将该模型应用到自然贮存延伸率预测和寿命评估中去,该模型具有很好的相关性。在该模型下某自然贮存HTPB推进剂10年后延伸率满足要求的概率为0.9。该模型可以用来预测HTPB推进剂的使用寿命。To study the change of HTPB propellant＇ s max-elongation and life assessment at a natural store condition, the dualistic linear regression model was built based on high temperature accelerated aging of HTPB in constant strain, with consideration of the characters of line model and index model. This model is used to predict elongation and life of propellant and has good correlativity. There is a kind of natural stored HTPB propellant which satisfies the elongation - request at the probability of 0.9 using this model. This model could be used to predict service life of HTPB propellant
