G-TWIMBAUTO: Digital Twins of Electric Motors for Cyber-Physical Test Benches

G-TWIMBAUTO explores the introduction of the digital twin paradigm in cyber-physical test benches for automotive and industrial applications. The theoretical developments in this project are validated by means of numerical simulation and experiments in test benches for electric motors, in which the components under test are interfaced to virtual environments following a Model-Based System Testing approach.

The project started in 2021 at the Mechanical Engineering Laboratory (Laboratorio de Ingeniería Mecánica - LIM) of University of A Coruña (Spain). Researchers from Siemens Digital Industries Software (Belgium) and GKN Automotive Zumaia (Spain) have collaborated in its tasks.

Related Projects

G-TWIMBAUTO builds upon the expertise acquired in other projects previously developed at LIM:

	- The HiPERFORM project (2018-2021), funded by the European Union, dealt with the development of efficient Wide Band Gap (WBG) components for their use in electronic devices. In this project, researchers at LIM used effective co-simulation algorithms and thermal models of e-powertrain componens to test the performance of electric vehicles that use this new technology.
	- COSIMBAUTO (2018-2021), funded by the Ministry of Economy of Spain, investigated co-simulation schemes suitable for soft- and hard-real-time simulation of multiphysics systems in Hardware/Human-in-the-Loop (HiL) and System-in-the-Loop (SiTL) test benches, with special focus on automotive applications.
