Nonlinear circuit design of damping boring bar based on MULTISIM

Chatter easily exits during cutting process of damping boring bar. In order to save development cycle of damping boring bar circuit, nonlinear model of damping boring bar is established with help of SIMULINK model of MATLAB. Modular layout of corresponding arithmetic logic unit is designed under modular design. Layout of arithmetic logic unit contributes to design of circuit. The circuit of system is designed and simulated with MULTISIM. The development of circuit contributes to research on control strategy concerning chatter. It also provides a new approach to pulling progress of nonlinear dynamics.
