Vibration-based Monitoring of Interactions at Cutting Wheel – Detecting Wear (C07#)

子项目C7开发了一个监测系统，利用基于振动的功能，在切割过程中检测和识别切割轮的磨损和损坏，以有效使用隧道掘进机。使用具有不同详细程度的数值模型以及实验研究，分析振动的不同原因，并生成数据用于切割轮的基于数据的分析。对于特定应用，应用模式识别和新奇检测的方法，并使其适于基于未损坏状态的数据最终实现对盘磨损的监测。

Subproject C7 develops a monitoring system to detect and identify wear and damages at the cutting wheel during the cutting process using vibration-based features to enable efficient use of tunnel boring machines. Using numerical models with different level of detail as well as experimental investigations, different causes of vibration are analyzed, and data is generated for the data-based analysis of the cutting wheel. For the specific application, methods of pattern recognition and novelty detection are applied and adapted to ultimately enable the monitoring of disk wear, based on data of the undamaged state.
