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 determination of fitting equation of the paste propellant constitutive equation, the Bagley correction method was introduced, and the error was corrected according to the Bailey correction parameters to re-fit the constitutive equation to reduce the viscosity of the paste propellant The experimental error came. The introduction of Bagley correction method will be fitted with the error of about 8% of the constitutive equation amended to reduce the error of <2%, obtained by the constitutive equation obtained by the function curve and experimental measurements in good agreement . The results show that the Bailey error correction method is effective and the accuracy of the constitutive equation of the paste propellant is improved to a certain extent.
