Evaluation of the Energy Balance on Test Bench with Open Power Flow and Closed Power Flow for Testing of Transmission

The article deals with the diagram of the disposition of components and the creation of kinematic bonds of the test benches for transmission systems. The source of the drive on test benches is an electric motor. The article describes the configuration of components and the creation of kinematic bonds for the test bench with an open flow of mechanical power. The test bench also includes a dynamometer in addition to the electric motor. The article is also described an assembly procedure and creation kinematic bonds for test bench with a closed flow of mechanical power. In this, test bench used only an electric motor without a dynamometer. The electric motor is the same for both test benches. The kinematics of test benches is modeled and calculated in the Swiss program KissSys/KissSoft. As a result, the article deals with evaluation the energy balance of the individual test benches, especially by evaluation the energy balance of the electric motor.
