Dynamics Research on Tape Feeder of Placement Machine

Abstract

Based on multi-body dynamics, the virtual prototype model of the tape feeder is set up, and the impact of the external torque and the friction coefficient on the whole system is analyzed. Simulation results show that the external torque has great influence on the required motor torque: when the external torque increases from 50N.mm to 200N.mm, the required motor torque increases from 75.217N.mm to 223.98N.mm. The friction damping also has great influence on the motor torque: when the dynamic friction coefficient increases from 0.001 to 0.009 and the static friction coefficient increases from 0.003 to 0.011, the required motor torque increases from 106.92N.mm to 158.81 N.mm.
