| 摘 要： | 以某固体火箭发动机推力向量控制系统摆动接头的单珠承载试验模型为计算模型,采用摩擦接触问题的Lagrange乘子法与弹塑性耦合的有限元理论,计算分析了摆动接头阳球试件在不同强化层厚度下的接触应力、变形及破坏机理；为降低系统摆动力矩,同时考虑大尺寸球面的表面强化和加工工艺,提出了满足接触性能的阳球表面强化层为1～1.4mm...

| Abstract: | In this paper,a single ball load-bearing experiment model of the swing joint of thrust vector control system in a solid propellant rocket motor was used as computation model.By using the Lagrangian multiplier method for friction contact question,and elasto-plastic coupling's finite element method,the contact stress,deformation and destruct principle under different thickness of strengthening layer of the test swing joint convex sphere were computed and analyzed.To reduce system swing moment,and consider man... |
