Current requirements for the reduction of CO₂ emissions, as well as for the improvement of durability and reliability of sociotechnical systems such as passenger cars, lead to an increase in development effort in order to increase efficiency and system lifetime. Tribological systems play an essential role in the development of sociotechnical systems, but have proved to be particularly complex. The development of tribological systems, as part of the overall system under development, is an interdisciplinary effort. Involvement of solid mechanics, fluid mechanics, rheology, and many more scientific disciplines is essential to cope with the high number of nonlinear relationships, which often cause unpredictable system behavior. This paper contributes to the scientific field of tribology by introducing concepts of model‐based systems engineering for the specific case of elastohydrodynamic lubrication states. The elastohydrodynamic lubrication state of tribological system has been chosen as example to show how system models can be used to better describe the behavior of a system by connecting several specific models. In order to gain an overview of the models used in tribological system development, a system cube was used to structure the models. The system cube enabled gaps and overlapping model zones to be identified. Finally, the role of system models in development and the benefit of using system models to solve problems that cannot be solved by a single technical discipline but only in an interdisciplinary effort are discussed. An approach to connect models and methods to describe a system in an elastohydrodynamic lubrication state is presented.

摩擦学系统开发中的系统模型和模型分类

减少CO _2的当前要求排放以及改善诸如乘用车之类的社会技术系统的耐用性和可靠性，导致开发工作量增加，以提高效率和系统寿命。摩擦学系统在社会技术系统的发展中起着至关重要的作用，但事实证明它特别复杂。作为正在开发的整个系统的一部分，摩擦学系统的开发是一项跨学科的工作。涉及固体力学，流体力学，流变学和许多其他科学学科对于应对大量的非线性关系至关重要，这些非线性关系通常会导致无法预测的系统行为。本文通过针对弹性流体动力润滑状态的特定情况引入基于模型的系统工程的概念，为摩擦学的科学领域做出了贡献。已选择摩擦学系统的弹性流体动力润滑状态作为示例，以显示如何通过连接多个特定模型来使用系统模型更好地描述系统的行为。为了获得对摩擦系统开发中使用的模型的概述，使用了系统立方体来构建模型。系统多维数据集可以识别差距和重叠的模型区域。最后，讨论了系统模型在开发中的作用以及使用系统模型解决无法由单个技术学科解决的问题，而只能通过跨学科的努力来解决的好处。
