Usage of synthetic generated and tactile measured flank micro geometry in ROMAX and TE validation via FE simulation and measurement in a torque test rig

The presentation deals with the usage of synthetic generated and also tactile measured flank micro geometry in a simulation dealing with the vibration excitation due to transmission error (TE) in the gear box. Whith imported flank geometry the analysis of so called ghost frequencies is demonstrated via TE calculation over all teeth.The simulation is validated via a finite element simulation and a TE measurement using a torque test rig. In the simulation the tooth contact is determined by the penetration on flank surfaces based on an imported maesurement based point cloud.
