N2 - The overall objective of the Speed2E joint research project is the development and construction of a high-speed powertrain for use in purely electrically-driven automobiles. Increasing the motor speed up to 30,000 rpm leads to a higher power density, efficiency and profitability of electrified powertrains. Within the context of the project, a highly functional powertrain test rig has been developed at the Technical University of Munich to investigate the challenges of high operating speeds in terms of efficiency, lubrication distribution and vibration behaviour. To this end, numerous test gear sets have been designed for the transmission input gear stage to rate the influence of different gear geometries on the aforementioned aspects. The vibration behaviour has been investigated based on comprehensive structure-borne and airborne noise measurements on the test rig. A comparison of the vibration behaviour is then presented to derive low excitation and low noise gear geometries for high-speed concepts of electromechanical powertrains.
