摘　　要：建立了丝杠冷滚打成形的有限元模型,使用ABAQUS软件模拟其成形过程。首先在仿真结果的基础上,设计正交试验,研究冷滚打过程中工艺参数对滚打深度和隆起高度的影响关系;然后分别建立滚打深度和隆起高度与工艺参数之间的多元回归模型,并进行显著性检验;最后利用自行设计的滚打装置进行丝杠冷滚打试验,验证了模型的有效性。研究结果为通过控制工艺参数形成精确的零部件轮廓提供理论基础,对丝杠冷滚打成形有重要的指导意义。A FEM model of the lead screw cold roll beating forming processes was built,the ABAQUS software was used to simulate the forming processes.Firstly,based on simulation results,the orthogonal test was designed,influences of processing parameters on forces,beating depths and bulging heights of cold roll beating processes were studied.Then multivariate regression models of beating depth and bulging height to process parameters were established,and significance tests for regression effects were carried out.Finally,with the self developed experimental device,lead screw cold roll beating experiments were carried out to verify the effectiveness of the models,which is of important guiding significances for forming accurate profiles of lead screw by control processing parameters.
