Abstract

Based on the basic principle of statistical energy analysis, the concept of equivalent SEA is put forward and the equivalent SEA model of gear box is established. The vibration response and radiation noise of the gearbox under the gear dynamic load excitation are studied. The modal density and loss factor of each subsystem are determined by the virtual test method and the numerical calculation method of backflow of power flow. The modified statistical energy parameters are assigned to the SEA model, obtaining the structural vibration responses and the radiation noise spectrum of each subsystem of the gearbox.
