Stick-slip vibration characteristic of PDC bit cutting composite strata based on discrete element method

For the problem of stick-slip vibration caused by hard rock formation in the process of drill bit penetrating in coal mine, and the discrete element method (DEM) was employed to study the rock cutting performance and stick-slip vibration behavior of PDC bit drilling in five typical different hardnes...
