项目摘要

In the development of mechanical units containing tribological components, the first step of materials selection or pre-selection is based on simple test configurations such as pin-on-disk or block-on-ring configurations. The following development reflects the complexity of geometry and conditions of operation by passing thru 5 additional categories until the final unit is approved for use. This approach ensures on the one hand from a reliable and safe operation of the unit in the application, but on the other hand, involves enormous experimental efforts and costs. By identifying correlations between different test categories and ultimately modeling and simulation, the relationships between different test categories will be investigated and described. The procedure in the proposed project is to investigate these relationships in the behavior by using different experimental standards and intermediate geometry in the first two categories (VI and V) of tribological testing and finally predict the system properties in category V based on simple tests performed in category VI. The ultimate aim of the work is to replace the experimental effort in category V completely by simulations und finally reduce cost and time in the development cycle of tribological components.In particular, we would like to address the following goals:* Creation of a FE micro model for homogenizing the thermal, mechanical and tribological properties.* Creation of a thermo-mechanical finite element model to simulate the temperature distribution of the deformation and wear.* Description of the heat balance in a standard experimental set up (block-on-ring).* Description of thermally and mechanically induced deformations in a standard experimental set up .* Description of the heat balance and the deformations in a final component design oriented test set.* Description of the interaction of temperature and tribological properties.* Comparison of the tribological properties of the different systems and investigate the correlation based on the heat balance

在开发包含摩擦学部件的机械单元时，材料选择或预选的第一步是基于简单的测试配置，例如销盘或块环配置。以下发展反映了几何形状和操作条件的复杂性，通过5个额外的类别，直到最终装置被批准使用。这种方法一方面确保了应用中单元的可靠和安全操作，但另一方面涉及巨大的实验努力和成本。通过识别不同测试类别之间的相关性并最终建模和仿真，将研究和描述不同测试类别之间的关系。在拟议的项目中的程序是调查这些关系的行为，通过使用不同的实验标准和中间几何在前两类（VI和V）的摩擦学测试，并最终预测在V类的基础上进行简单的测试在VI类的系统性能。本研究的最终目标是通过模拟完全取代第V类的实验工作，最终降低摩擦学部件开发周期的成本和时间。特别是，我们希望解决以下目标：* 创建有限元微观模型，以分析热、机械和摩擦学特性。*建立热-机械有限元模型，模拟变形和磨损的温度分布。*描述标准实验装置（块-环）中的热平衡。*在标准实验装置中描述热和机械引起的变形。描述最终组件设计导向测试装置中的热平衡和变形。*温度和摩擦学特性相互作用的描述。*比较了不同体系的摩擦学性能，并基于热平衡研究了相关性
