摘要:

数字孪生模型能够有效地促进实际产品与产品模型间的虚实交互。针对调心滚子轴承套圈磨削过程中的磨削力,通过对磨削工作区各构件进行动力学与接触算法建模以及刚柔耦合处理,构建了轴承套圈沟道磨削加工数字孪生模型,完成了轴承套圈磨削工作区域在数字空间中的虚拟映射。并使用该模型对砂轮线速度、工件转速等工艺参数进行了分析与试验,证明了所构建数字孪生模型具有一定的有效性。该模型具有高保真性,可用于理解、预测和优化真实系统。

Abstract:

The digital twin model can effectively promote the virtual-real interaction between the actual product and the product model. Aiming at the grinding force generated in the grinding process of spherical roller bearings, this paper constructs the bearing ring raceway grinding process by performing dynamics, contact algorithm modeling and rigid-flexible coupling treatment on the components of the grinding work area. The digital twin model completes the virtual mapping of the grinding work area of the bearing ring in the digital space. The model is used to analyze and test the process parameters such as the grinding wheel linear speed and the workpiece speed, which proves the validity of the digital twin model constructed. The model has high fidelity and can be used to understand, predict and optimize real systems.

Key words: dynamics, virtual mapping, digital twin model, grinding force, process parameters
