基于旋压和惯性自旋压原理,设计出精密成型装置,应用有限元分析方法,数值模拟了非均匀壁厚工件成型的工艺过程,重点分析了金属变形区的等效应力和等效应变的变化情况,结果表明,单次多道自旋成型工艺合理,精密成型装置设计可行,具有一定的推广价值。 Based on the principle of spinning and inertial spin pressure, a precision forming device is designed. The finite element method is used to simulate the forming process of non-uniform wall thickness workpiece. The stress and equivalent strain of metal deformation zone are analyzed emphatically The results show that the single multi-channel spin molding process is reasonable and the design of the precision molding device is feasible and has certain promotion value.
