Metal forming or shaping processes, such as sheet metal forming and bulk forming, are widely used in many industries including automotive industry. Before computational simulations were widely used in the field of metal forming industry, the trial-and-error based empirical approach was conventionally applied to the optimization of the metal forming process and product. The most commonly employed numerical approach in the metal forming process for robust process optimization is the finite element analysis. Friction, one of the parameters that significantly affect the accuracy of numerical analysis, depends on several variants such as surface quality, contact pressure, lubrication, deformation, and the forming environment. Despite the complexity and difficulty of identifying friction mechanisms, accurate friction models are essential and hence have been proposed by numerous researchers. In this paper, the friction models in the previous studies are reviewed by categorizing them into the boundary lubrication condition and mixed-boundary lubrication condition according to their evaluative influences on friction. Since friction models have been proposed based on the contact theories, an overview on the contact models is also included in this paper. In addition, the contribution of several parameters on the friction such as surface roughness and material properties of the tool, adhesion, contact pressure, sliding speed, bulk deformation is also discussed. This review paper aims to provide an understanding and insight into the friction modeling and simulation along with associated friction experiments.

汽车金属成形摩擦与润滑综述:实验与建模

金属成形或成型工艺,例如钣金成形和块体成形,广泛应用于包括汽车工业在内的许多行业。在计算模拟广泛应用于金属成形工业领域之前,基于试错法的经验方法通常应用于金属成形工艺和产品的优化。在金属成形过程中最常用的数值方法是有限元分析。摩擦是显着影响数值分析精度的参数之一,它取决于多种变量,例如表面质量、接触压力、润滑、变形和成型环境。尽管识别摩擦机制复杂且困难,精确的摩擦模型是必不可少的,因此已被众多研究人员提出。在本文中,根据对摩擦的评估影响,将以往研究中的摩擦模型分为边界润滑条件和混合边界润滑条件。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。在本文中,根据对摩擦的评估影响,将以往研究中的摩擦模型分为边界润滑条件和混合边界润滑条件。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。在本文中,根据对摩擦的评估影响,将以往研究中的摩擦模型分为边界润滑条件和混合边界润滑条件。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。回顾以往研究中的摩擦模型,根据它们对摩擦的评估影响,将它们分为边界润滑条件和混合边界润滑条件。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。回顾以往研究中的摩擦模型,根据它们对摩擦的评估影响,将它们分为边界润滑条件和混合边界润滑条件。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。由于摩擦模型是基于接触理论提出的,因此本文还对接触模型进行了概述。此外,还讨论了几个参数对摩擦的贡献,例如工具的表面粗糙度和材料特性、附着力、接触压力、滑动速度、体积变形。这篇评论论文旨在提供对摩擦建模和模拟以及相关摩擦实验的理解和洞察。
