Innovative Configuration of the Closed-Loop Test Stand 2015-01-1092

The purpose of the article is to describe different possibilities of the innovative concept of the closed-loop test rig. The performed tests will be demonstrated with the example of measured data.
Firstly the article will describe in detail the design of the test stand and both torque units. The power flow in the closed-loop circuit will be described and measured to find out the power losses of all parts. The measurement will be done for manual and planetary pretensioning mechanism. The comparison of the overall efficiency and demanded power for both torque units will be given.
For evaluation of gearbox efficiency, the magnitude of power losses will be evaluated for different revolutions, torque levels and shifted speeds.
For a long term tests, the unmanned operation is prepared. For this purpose is the stand equipped with electromechanical shift robots.
The description of its concept and functioning will be part of the paper.
