Acoustic and Vibration Response Analysis of Heavy-Duty Gearbox
Original language description
The presented paper deals with determination of acoustic and vibration response of heavy-duty gearbox housing on the defined force excitation. The analysis is performed by both, numerical and experimental approach. The results from both approaches are compared to validate numerical approach for the pur-pose to use numerical model for design optimization and further for multi-body simulations. The excitation is applied to the area of bearing to simulate the real character of the excitation, which is transmitted from the gear mesh contact stiff-ness, which is changing due to actual geometry of teeth in contact, via gears and shafts to bearings and further to the housing. The same boundary conditions are applied for both approaches. Because the vibrations and the acoustic emissions are directly related to each other, the surface normal acceleration in critical loca-tions are compared first. When the surface normal acceleration is compared, the sound pressure level in defined locations is evaluated. This article systematically describes the prediction of vibro-acoustics behaviour of heavy-duty gearbox housing by using two different levels of approach, which can be used for design optimization afterwards. The technical experiment with optimized housing has not been performed yet.
