Multiscale Modeling, Simulation and Optimization of Cutting Tools Regarding their Tribological Behavior (C06*)

建立了从微观到宏观的隧道掘进机刀具磨损模型。在微观尺度上，基于离散化的代表性微观结构开发了仿真模型。在宏观尺度上，发展了描述磨损的唯象模型来模拟刀具部件。在子项目C5中获得的实验结果的基础上验证这里开发的数值模型，并应用于识别改进的切削刀具的概念，使用数值优化策略。

The wear process of cutting tools of tunnel boring machines is modeled across the scales from the microstructure to the macroscopic tool components. At the microscale, simulation models are developed based on discretized representative microstructures. At the macroscale, phenomenological models for the description of wear are developed to simulate the tool components. The numerical models developed here are validated based on the experimental results obtained in Subproject C5 and applied to identify improved cutting tool concepts using numerical optimization strategies.
