| 摘 要： | 喷管锥段是火箭发动机能量转化和推力向量控制机构,一般采用剪切旋压加工。采用ABAQUS有限元软件,建立了高强铝合金7A52锥形件剪切旋压模型;采用单一变量法,分析了旋压间隙、旋轮进给比、旋轮圆角半径对锥形件剪切旋压壁厚差的影响,为锥形件的制造提供一定的指导。

| Abstract: | The nozzle cone is the energy conversion and thrust vector control mechanism for the rocket engine,which is normally processed by use of shear spinning process.The sheafing spinning model for high strength 7A52 aluminum alloy conical part has been established on basis of ABAQUS finite element software.The single variable method has been adopted to analyze the influence of the spinning gap,the roller feeding rate and the roller roundness radius on the shear spinning wall thickness difference for conical part.It provides certain reference for the manufacture of conical part. |
