Successful Commissioning of the New Powertrain Test Rig of LKT

At the beginning of October 2018, a new powertrain test rig was delivered to us. This test rig, produced by our Japanese cooperation partner HORIBA, allows the scientific staff of the Chair of Automotive Engineering (LKT) and of Auto Mobil Forschung Dresden GmbH (AMFD) to expand into completely new investigation possibilities in the area of powertrain analysis. On the one hand, actual gearboxes like main gearboxes, transfer boxes and axles drive can be tested. On the other hand, further components of the drivetrain like side shafts or flywheels can be examined. This state-of-the-art test rig goes along the trend of replacing the ICE by a powerful high-dynamic electric motor.

Remarkable for this test rig, which successfully passed commissioning in November 2018, is the fact, that high-dynamic permanent magnet synchronous motors are used distinguished by extremely low rotational moment of inertia compared to their power density. In this way, many high demanding and high-dynamic phenomena of the powertrain are possible to be tested. For instance, the technique of Engine Torque Pulsation Simulation (HORIBA ETPS) or wheel-slip simulation can be investigated.

By deployment of this new powertrain test rig, fundamental current and future questions regarding the topics Driveability and efficiency will be answered. In cooperation with HORIBA we will conduct studies with the test rig and do research even at the test rig. Further upgrades for the test rig like integration of E-drives by battery simulation and development of other applications are planned at the moment. By completion of the second stage of construction of our vehicle testing facility (FVZ), the powertrain test rig will be moved to this location. Then, some can see the main upgrade up to five electric motors for this test stand. In that way, almost all of the powertrain configurations available at the market can be realized and analyzed.

In terms of further queries regarding this test rig, do not hesitate to contact Dipl.-Ing. Marcus Steinbeiß und Dipl.-Ing. Henrik Schmidt. We are looking forward to presenting our new powertrain test rig to you and discussing topics more in detail.
