STUDY REVIEW ON THE INTERACTION BETWEEN DISK CUTTER AND ROCK

Research purpose:As a main tool to cut rock, disc cutter was mainly assembled on cutting wheel of TBM, mixed shield and rock shield. It was vitally theoretical significant and usefully valuable to study interaction between disc cutter and rock, in which studying cutting mechanism of disc cutter, guiding design of cutter and cutting wheel, improving cutting efficiency and driving performance and decreasing power consumption were included. Research method:abundant documents synthetical analysis and research. Research result:Fundamental cutting mechanism of the disc cutter , section style and geometric parameters were analyzed firstly. Then research achievements of inner and foreign were overviewed on interaction mechanism, cutting forces and driving performance prediction, also mechanical aspects and geological aspects as main influencing factors on interaction between cutter and rock were pointed out. Research conclusion: Finally existing problems and future research directions were analyzed which was expected to speed our domestication of TBM and shield.
