On our ATESTEO HiL test benches we examine vehicle components under real operating conditions for example vibration dampers, transmissions and transfer cases. The requirements for commercial vehicles are subject to constant change. In addition to durability, comfort is of decisive importance. The NVH behaviour is particularly decisive in this respect. Corresponding optimizations lead to a lower vibration load on the driver. The drive train is a significant source of vibration and noise.
In order to test and tune new components, validation is becoming increasingly important. Due to the development of new types of vehicle drives and an increasing proportion of mechatronic systems, the requirements placed on individual components are becoming more and more complex and the tests more and more extensive.
The HiL test bench makes it possible to transfer the system behavior of the drivetrain to the components. For this purpose, a test bench model exists which is coupled with a vehicle simulation model. The simulated interactions are transferred from highly dynamic electric machines to the test object.
