Abstract [en]

Dynamic transmission error (DTE) is widely accepted as the source of gear whine noise, therefore its reduction is essential for NVH optimization of drivelines. While most studies in hypoid gear dynamics concentrate on the gears only, this paper takes into account the additional effect of other driveline components and examines their contribution to the DTE. The analytical model developed in this paper consists of a hypoid gear pair connected to a simple structure with well-defined modal behaviour. A test rig is specifically designed to validate the model. In the rig, the pinion rotates only along one axis while the gear is also allowed to have translational motion induced by a rigid body modes on an elastic foundation. This model could help identifying the most influential parameters in terms of the mode and DTE interaction and thereby improve the NVH performance of driveline units.
