기어시스템의 backlash에 대한 동특성 해석

Abstract

This paper proposes backlash model as a nonlinear spring which has a large torsional stiffness. To analyze nonlinear system, the describing method is adopted. By this method the system is linearized and its dynamic characteristics, resonance and antiresonance are predicted. According to the value of backlash, simulation are carried out for time responses and frequency responses and results are compared with experimental results.
