During the MBS Tech Days 2021, Robert Kalcher from AMSD Advanced Mechatronic System Development held a presentation titled "Modeling of BEV Powertrain Mounts in BMW Complete Vehicles using Simpack MBS".
In his presentation Robert talks about the issue of legal requirements and based on the general trend towards electrification, the amount of battery electric vehicles (BEVs) within the fleets of vehicle manufacturers increased steadily in recent times.
BMW is no exception with its current series production BEVs i3, i4, iX3, and iX. In general, BEVs deploy electric axle drives (EADs) as powertrain units at the front and/or rear axle. Furthermore, EADs are usually mounted to the vehicle's body or subframe via elastomer mounts.
Since such BEV powertrain mounts significantly influence the vibration comfort of the complete vehicle, the elastomer mount modeling and parameterization is a crucial and challenging task. Therefore, the work at hand deals with the MBS modeling of elastomer mounts, the associated fitting, and the subsequent incorporation of complete vehicle models within Simpack MBS software.
The virtual development process regarding vibration comfort using the module Simpack Wizard and its corresponding automotive database will be presented based on a case study.
Robert Kalcher is a PhD student at the Institute of Mechanics, Faculty of Mechanical Engineering and Economic Sciences at the Graz University of Technology. There he received his BSc and MSc in Civil Engineering in 2009 and 2013, respectively.
In 2014 Robert received a Diploma Degree in Automotive Engineering from the University of Applied Sciences FH Joanneum Graz.
Currently, Robert works at AMSD Advanced Mechatronic System Development as a Development and Simulation Engineer for the automotive sector. Robert's research interests include nonlinear dynamics and multi-body systems.
