摘要：Considering the time-varying support stiffness of bearings of the sun gear and the carrier, the lumped-parameter method was used to establish a coupling dynamics model of planetary gear transmission with meshing beyond pitch point. The vibration acceleration responses of the sun gear and the carrier were obtained by using Runge-Kutta method. The theoretical results show that the vibration acceleration values with time-varying support stiffness are larger than that with constant support stiffness. The experimental study using a mechanical power closed test rig was carried out. The experimental signals were denoised by the wavelet theory. There is an error of 16.27% between theoretical and experimental values in horizontal direction, which is in the allowed range; the values have large error in vertical direction due to the influence of gravity. The experiment results also show that the vibration acceleration values with the time-varying support stiffness are closer to the experimental results, which indicates that the time-variant of support stiffness is not ignorable. © 2017, Central South University Press.
