Structural Behavior Examination of Frequently Used Solid Propellant Sections Under Centrifugal Loading Using Response Surface Method
Keywords:
Solid Rocket Motor, Centrifugal Loading, Finite Element Analysis, Viscoelasticity, Response Surface MethodAbstract
This research aims to examine structural responses of frequently used solid propellant sections such as tubular, star, slotted, wagon wheel, and anchor subjected to centrifugal acceleration load. Viscoelastic finite element models of the grains having different dimensions are constructed and solved in Abaqus environment using in house parametric Python scripts prepared within the content of this work. Validation of the finite element models is accomplished comparing finite element results with an analytical equation found from literature. Finally, different response surfaces are constructed in Minitab environment to determine effect of grain cross-section parameters on von Mises stress level of the propellant. Thus, the most effective cross-section parameters on von Mises stress are determined for the examined grain shapes.
