摘要：
The study on natural frequency sensitivities to system parameters of two stage planetary gear train with double helical tooth was not reported, though natural frequency sensitivities of the one stage planetary gear were investigated by some researchers. In this paper, parameters under consideration mainly include mesh stiffnesses. Using the well-defined vibration mode properties of tuned two stage planetary gears, the eigensensitivities are calculated and expressed in simple, exact formulae. These formulae connect natural frequency sensitivity with the modal strain and provide efficient means to determine the sensitivity to all stiffness parameters by inspection of the modal energy distribution.
