“…The research results of Rostami (2013), Wu (2011) and Wang et al (2011) show that the normal load distribution on the contact arc length between the disc cutter and hard rock is approximately a parabolic distribution. According to this distribution model, the forces F r 0 and F n 0 can be deduced as follows (Wang et al, 2011):…”

“…Herrenknecht developed a scraper with wear detection function, and the wear amount of a cutter was detected by comparing the difference in protruding stroke before and after the wear (Hassanpour, 2017). Wilt obtained cutter wear information by using a special odor additive called MOLYUAN (Shi, 2015), and Robbins monitored the cutter running status based on collective real-time data of the rotational speed, temperature and vibration (Wang, 2011;Entacher, 2013). Lan (Lan, 2016;Lan, 2019) and others realized detection of cutter wear and speed with an eddy-current sensor solution.…”

Mud-caking of the cutterhead in a tunnel boring machine (TBM) has been commonly encountered when a TBM is excavating through strongly weathered rock or clay. Not only the opening of cutterhead could be blocked to cause problem for muck flowing through, mud-caking of a cutterhead will also lead to the increase of thrust and torque, as well as compromise of tunneling efficiency. To predict the mud-caking status in real time, a prediction model was established based on cutter temperature characteristics, and a bus-based detection system was designed to monitor cutter wear and temperature in tunneling. Such prediction model and detection system were verified on an earth pressure balance (EPB) TBM at a Shenzhen metro project. The research demonstrated that the detection system performed its function of monitoring cutter wear and temperature changes in real time. A dynamic prediction of cutterhead mud-caking status was also proved using the prediction model.
