| 摘 要： | 基于某发动机柔性喷管结构，用弹簧模型替代柔性接头，建立计算模型，对不同控制力作用下的柔性喷扩张段支耳的轴向和径向刚度进行了三维有元分析计算，本计算分析，对固体发动机推力向量控制有一定的参考价值。

| Abstract: | On the basis of solid rocket motor flexible nozzle model in which the nozzle structure is simplified by replacing the flexible joint with spring model, the stiffness of divergent section supporting lug under various axial and radial actuation is analyzed and caculated with three dimensional finite element method. The numerical caculation shows that these results and analysis can play an important part on the thrust vector control in SRM. |
