Influence of tooth profile errors and subharmonic resonance in helical gears rattle by Yutaka YOSHITAKE, Toshiyuki KOGA, Natsumi TAGAWA, Shintaro SOBU, Takahiro HARANO, Yasuhiko OUGIYA

“…As a result, the followings were made clear. (1) About the resonance amplitudes caused by tooth profile errors, those in the gears with middle concave tooth profile error are generally larger than those in the gears with middle convex tooth profile error. (2) About the resonance amplitude caused by the torque variation, there is little difference between the gears with the middle concave tooth profile error and those with the middle convex tooth profile error. (3) In the case without torque variation, there is a possibility that 1/2th-subharmonic vibration and 1/3th-subharmonic vibration occur because of tooth profile error. (4) When torque variation is increased, 1/3th-subharmonic vibration caused by tooth profile error degenerates. (5) In the near region where the 1/2th-subharmonic vibration generates, by the interaction of the vibrational force by the tooth profile error and the torque variation, many unstable branches are created, and chaos occurs.…”

Study on the vibration characteristics of bladed disks (Effect of damping variation on the resonant responses of bladed disks) by Yasutomo KANEKO, Riku YOSHIDA, Toshio WATANABE, Tatsuya FURUKAWA

“…However, in a bladed disk with the blade root inserted into the disk groove, the damping mistuning caused by the partial contact between the root and groove in rotation cannot be neglected in predicting the resonant response of the bladed disk. Therefore, in this study, incorporating the damping mistuning into the FMM (Fundamental Mistuning Model), the frequency response analysis of the bladed disk is systematically carried out. …”
