To become independent of weather conditions and the local and seasonal variation, it is necessary to shift particular tests to a climatic wind tunnel.
Although this offers an ideal environment for precise and reproducible results, many tests need to be performed in order to acquire knowledge about the differences between real road investigations and binäre optionen franco pellegrino signale tunnel experiments. It is the work of Method developers to properly transfer specified road tests to the test facility such that comparable results are obtained. These details will be discussed in the first chapter.
An important aspect, within this objective, is the realistic simulation of drive resistance on the road by dynamometers. Therefore the different forces, contributing to the drive resistance on the road, are determined in order to simulate the realistic load on the vehicle drive train by the electric drive units of the dynamometers. To increase the accuracy of the load simulation, a special feature has been added to the dyno-control.
This feature includes the influence of air-density on the drive resistance at a given environmental temperature, pressure and humidity. The branching fractions are measured to be 4.
