摘　　要：对HTPB推进剂高温加速寿命试验的老化起点进行了修正,并将Arrhenius方程中活化能与温度的函数关系修正为多项式形式。通过2种HTPB推进剂老化试验数据的回归结果得到修正活化能方法的老化模型,外推出25℃下的贮存寿命分别为12.8 a和11 a,与常温外推试验数据相符,且误差小于传统Arrhenius方法。The aging starting point of the high temperature accelerated life test of HTPB propellant was modified,and the activation energy of the Arrhenius equation was modified to be a polynomial.The aging model of the modified activation energy method was obtained by the regression results of two kinds of HTPB propellant based on the aging test data,and the storage life of the new method is 12.8 a and 11 a respectively,which is consistent with the data from the temperature extrapolation test,and the error of which is less than the traditional Arrhenius method.
