 note = {Gear rattle of multi-step helical gear system is treated. Mesh stiffness variations and higher harmonics of driving torque are considered in the system. The effects of higher harmonics of driving torque are studied by numerical analysis. As a result, the followings were made clear. (1) In the resonance region of lower mode, when the frequency of driving torque is nearly equal to the one which is the natural frequency of higher mode divided by some integer, the response contains the higher mode and its amplitude of acceleration becomes large. However this phenomenon is not so affected by the higher harmonics of driving torque. (2) First harmonic of driving torque generates higher harmonic resonance and higher harmonic of driving torque generates the main resonance, hence the interaction of these two resonances makes the amplitude of the resonance large. (3) Because of interaction of higher harmonics of driving torque and mesh stiffness variation, resonances like gear noise occur with many side-bands in low frequency region, and the region of the rattles becomes wide. (4) Gear rattles in the case of small constant torque are almost chaos, and chaos by intermittency is recognized., 日本機械学会論文集. C編, 76(763), pp.475-482; 2010},
