Hardware in the Loop (HIL) Rig Design and Electrical Architecture

Abstract: Different types of machines are tested utilizing so called Hardware In the Loop simulation. To perform HIL-simulation a rig is used consisting of different types of hardware and software. Some of the hardware that are used during a simulation is located inside an EMS box. The box has not been properly updated since 2004, no documentation of changes has been made and often many errors occurs during simulations due to the lack of traceability. During this project a new structure of the EMS box has been designed with modifications to eliminate existing problems, prevent similar problems to occur in the future and improve the usability of the system. A simulation was performed on the camshaft to test if there were any improvements. Most issues were solved but there were one problem that remained. Some noises existed and were rooted in the old box which undeniably remained in the new one.
