Nonlinear dynamical analysis of semi-active dynamic vibration absorbing boring bar system

For the boring bar’s chatter, based on the built-in damping boring bar, a type of magnetorheological semi-active dynamic vibration absorbing boring bar component was proposed. And a nonlinear dynamical model of absorbing boring bar was established. An analytical solution for the system's dynamical response is obtained by the multi-scale method, which is verified by the numerical solution, and the changes in the boring bar system parameters on the effect of dynamic characteristic was explored, the results provide the basis for the monitored control of the boring bar’s cutting chatter.
