| 摘 要： | 丝杠冷滚打成形是一种新型的绿色近净塑性成形技术,其中的变形力是冷滚打成形过程中一个非常重要的因素,不仅关系到材料的应力和应变,还是设备设计、验算工具强度、制定合理工艺制度的重要依据.基于仿真进行丝杠冷滚打变形力的研究,介绍丝杠冷滚打的原理,讨论基于 ABAQUS的有限元模型的建立,在此基础上进行了丝杠单次滚打正应力、切应力的仿真,进而获得了变形力及其分力随时间的变化情况,为后续研究奠定了基础.

| Abstract: | Lead-screw cold roll-beating is a new type of green near-shape plastic forming technology.The deformation force is of great importance,which not only can affect the strain & stress of the material but can provide important base for equipment design,verifying tool strength and making reasonable process.This paper focuses on preliminary study of deformation force based on simulation.Firstly,the principle of lead screw cold roll-beating is simply introduced,then the FEM mode in ABAQUS is built,then the normal ... |
