摘　　要：在膏体推进剂本构方程测定拟合过程中,引入巴格利(Bagley)修正方法,根据巴格利修正参数进行误差修正重新拟合本构方程,用于减小膏体推进剂粘度带来的实验误差。引入的巴格利修正方法将拟合得到的带有8%左右误差值的本构方程修正减小到误差<2%,由求得的本构方程得到的函数曲线与实验测量值吻合较好。结果表明,巴格利误差修正方法效果明显,在一定程度上提高了膏体推进剂本构方程的精度。In the process of fitting the constitutive equations, the Bagley correction method was brought in to obtain the correction parameters to refit the constitutive equation and reduce experimental errors caused by the viscosity of paste propellant. The experimental errors were reduced from 8% to less than 2% by using the Bagley correction method. The obtained curve of the constitutive equations were consistent with the experimental data. The results showed that the Bagley correction method had an obvious effect in improving the accuracy of the equation to a certain extent.
