By considering torque characteristics of variable-frequency motors and mesh stiffness as well as backlash nonlinearity in gear transmission,a dynamics model for the cutting system of shield tunneling machine with redundant drives was established. The fluctuation characteristics of torque loads and dynamic cutterhead driving torque in composite strata were analyzed.
