Abstract

Abstract:

On the basis of research results in the spiral compression and extension process of solid propellant， a new method was explored to establish a rheological model of solid propellant. To develop this new method， a least square method was used to fit the data obtained from the capillary rheometer test to achieve a preliminary solid propellant rheological constitutive model. The test process of the capillary rheometer was then simulated by using by a Polyflow finite element simulation software to correct the parameters of the rheological constitutive model so as to determine the final propellant rheological constitutive model. The rheological constitutive model of the propellant was established through a combination of experimental data fitting and finite element simulation. This lays a foundation for simulating the spiral extrusion process of solid propellant with a finite element method. The results indicated that there was only an error of around 10% between the real data and the data obtained from the simulation with the propellant rheological model by a combination of data fitting and numerical simulation. The obtained results were in good agreement with the expected results from the numerical simulation

Key words: propellant, rheological model, numerical simulation, least square
