The project aims to implement a digital twin in the powertrain area and combines various methodological preliminary work in the area of component development (interaction between structural and electrodynamics as well as acoustics in e-components) with overall system considerations. The main focus of the work is on simulation models for constant velocity joints in the drivetrains, which are subject to different loads as a result of e-mobility.
Questions relating to the identification of excitation mechanisms in the constant velocity joints and process parameters for influencing them are being investigated. The necessary experimental investigations are carried out on a cardan shaft test bench and a road-to-rig test bench.
The relevant work packages can be summarized as follows:

• Recording of measurement data (forces, torques, deflection angles, vibrations) of the drivetrain in cooperation with the Institute for Competence in AutoMobility (IKAM) & the Center for Method Development (CMD)
• Development of a detailed calculation method for the drivetrain with a focus on the constant velocity joints
• Reduction of the degree of complexity for implementing the method in the typical development process
