Original abstract
This paper is focused on the description of the dynamic behaviour of a single-stage gearbox when changing the operating load using numerical ap-proach. The numerical model, which is further discussed in the paper, combines FEM and MBS approach in the commercial software Ansys Workbench and Ad-ams with plugin GearAT. The key components are represented by flexible struc-tures – modally reduced bodies. The mesh conditions in the model can include the elastic behaviour of the gear rim, backlash and the influence of lubrication in the contact area. At the very beginning used approach was developed on a simple experimental gearbox. Subsequently, this methodology was applied to a complex train gearbox with the aim of optimizing its gearbox housing geometry. In a multi-body system, a series of operating simulations were performed on a virtual test rig. Based on the evaluation of normal surface velocity at selected points, the gearbox housing geometry was optimized.
