Abstract: In this paper, vibro-impact induced gear whine radiated by full hybrid transmission equipped with a multi-mesh gear train is investigated. For accurate simulations of the reducer gear vibrations, an integrated dynamic model of the transmission is established using professional software MASTA, on which compliance effects of gear pairs, bearings, transmission shafts and gearbox housing are counted for. Numerical analyses are carried out for dynamic responses of the hybrid transmission. Bench tests are also conducted for the present model validation. Computational effort is made to recognise parametrically resonant patterns that cause gear whine in experiment. An optimal tooth modification design is presented for the real multi-mesh gear train. It is shown by test results using the optimised reducer that gear whine responses of the gearboxes are considerably improved.

Keywords: multi-mesh gear train; transmission error; hybrid transmission; NVH.
