Abstract

The decision of a particular model of solid rocket motor nozzle control precision and flexible functioning of the pivot center drift and systems for power moment problems, using computer-aided design and analysis methods, and establish flexible nozzle coupled rigid-flexible multi-body dynamic model; to role of the body in the system activity for work on the axial load resistance, for sine wave, rectangular wave and triangular wave dynamics under the three kinds of incentive calculation, obtained and analyzed the system for dynamic moments, pivot center drift, supporting ear at a total displacement of, Coulomb friction torque, torque and inertia moment of deviation, while laying the foundation for the system optimization.
