摘　　要：本文主要针对铜合金药型罩零件进行强力旋压成形模拟仿真,基于Simufact/Ansys平台建立双锥形铜合金药型罩旋压三维有限元模型,通过数值模拟对药型罩强力旋压成形过程应力应变的分布规律分析,得出在药型罩的前端区域和双锥角过渡圆弧区域应力较大。以药型罩旋压后的应力应变分布为分析目标,得到旋轮安装角、旋轮半径及进给比对应力应变的影响规律。应用仿真优化的工艺参数进行旋压实验,实验结果表明药型罩满足精度要求,表明采用模拟仿真的方法和手段,能够对实际旋压加工起到指导作用。This paper mainly focuses on the simulation and experiments of spinning process of copper alloy charge liner.Based on the Simufact/Ansys platform,a three-dimensional finite element model of biconical copper alloy charge liner spinning is established.The stress and strain distribution of the charge liner,during the process of power spinning,is analyzed by numerical simulation method,and the conclusion of analysis is that higher stresses lie in the front area and biconical transition arc area of the charge liner.Aiming at stress-strain distribution of charge liner after spinning,the influences of spinning wheel installation angle,radius of the spinning wheel and the spinning wheel feed ratio on the stress and strain distribution are respectively obtained.The spinning experiments are carried out with the optimized process parameters,the experimental results show that the size of the charge liner meets the accuracy requirements,which indicates that the simulation method can play a guiding role in the actual spinning processing.
