Abstract: Abstract. A nonlinear torsional vibration model of precision harmonic drives is developed, incorporating stiffness degradation, static transmission errors, piece-wise backlash, and periodic torque excitation. Dynamic ...

Abstract: In this study, a physics-based fatigue wear model is proposed to evaluate the reliability and to predict the life of cumulative micropitting wear for lubricated conformal contacts on rough surfaces. The surface normal load, ...
