    摘要:

    基于Deform3D软件平台,针对薄壁件复合排大齿圈建立三维有限元模型,并模拟了不同工艺参数下的车削加工过程,得到了切削过程中的切削力分布场和温度场。通过分析不同切削参数下切削力和切削热的变化规律,得出切削深度和进给量对切削力影响较大,而切削速度对切削热的影响大于切削深度和进给量。该研究结果为进一步优化工艺参数和加工变形控制提供了依据。

    Abstract:

    Based on Deform3D software platform, a three-dimensional (3-D) finite element model (FEM) by aiming at the thin walled composite row of large gear ring was established, and then the turning process under different cutting parameters was simulated, the cutting force distribution and temperature fields in the cutting process were derived. By analyzing the change rule of cutting force and cutting heat in different cutting parameters, it was gotten that the cutting depth and feed affected much to the cutting force, while the influence of cutting speed on cutting heat was greater than that of cutting depth and feed. The research result has laid the foundation for further optimization of cutting parameters and machining deformation control. 
