固体火箭发动机喷管扩张段刚度分析及优化

Stiffness Analysis and Optimization for Exit Cone of Solid Rocket Nozzle

采用有限元素法对固体火箭发动机喷管扩张段进行了刚度特性分析，并从刚度出发提出了控制喷管推力方向的作动力方向的优化问题。最后，对某发动机喷管进行了分析。

The stifffness analysis for the exit cone of solid rocket nozzle using the finite element method is conducted. Based on the stiffness analysis,optimization about the direction for the direction for the actuating force of the thrust vector control (TVC) system is discussed. The optimum results for a solid rocket motor nozzle exit cone are obtained.
