Mute Transmission Noise - E-Drive Design with KISSsoft & RecurDyn

Noise Killers! E-Drive Design with KISSsoft & FunctionBay

Electric vehicles could represent up to 70% of all cars by 2050. To ensure the acceptance of their vibrational and acoustical characteristics, profound NVH analyses are the key to minimize vehicle excitations caused by specific e-Drive transmission designs.

During this live session KISSsoft & FunctionBay will present a common and continuous solution to design, analyze and optimize the NVH behavior of a gearbox used in an e-Drive system.

The workflow starts with a base transmission layout within the KISSdesign software environment. It is followed by a strength & stress analysis taking all relevant system deflections into account. Macro & micro geometry sizing will be done through a dedicated loaded tooth contact analysis (LTCA). After an overall efficiency calculation, the dynamic behavior of the complete system (modal analysis & forced response) will be assessed. Finally, the calculated load files and all relevant geometrical information are transferred from KISSdesign to the MBD – software RecurDyn from FunctionBay.

Within RecurDyn the NVH – simulation model is automatically generated based on the data supplied by KISSdesign. It includes flexible housings, pre calculated loads and all components representing the internal mass distribution of the system. The necessary simulations are also run automatically. An acoustic post – analysis can be performed by evaluating the calculated effective radiation power (ERP), the sound pressure levels (SPL) or by inspecting the related Campbell diagrams and more. If an optimization loop is required the above continuous workflow can be shortened by adjusting the gear design in KISSsoft and just updating the new calculated load files in RecurDyn.
