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

点击翻译按钮获取中文摘要

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.
