- Abstract
Background: The double-layer box for marine reducer connects the inner and outer boxes with vibration isolators, which can effectively reduce the vibration transmitted from the bearing end to the outer box and the base. Purpose: The analysis of the transfer path contribution of the double-layer box can enable researchers to control the vibration of the path with higher contribution, which plays an important guiding role in reducing vibration. In this study, the contribution of the vibration transfer path of the double-layer box for marine reducer is analyzed based on the force transmission rate of the vibration transfer path. Methods: First, a dynamic vibration transfer path model of the double-layer box is developed, and the vibration response is analyzed by solving the dynamic model. Then, the contribution of each vibration path is analyzed based on the force transmission rate and the main transfer path is identified. Finally, the finite element method is employed to verify the correctness of the dynamic model. Conclusions: The results revealed that the error between the simulation and theoretical results concerning the frequency corresponding to the peak acceleration was within 5%, and the transfer path that includes the rear vibration isolator is the main transfer path.
