Research Measuring Techniques

Driven by drastically tightened emission laws and rising fuel costs, great efforts are being made to increase the overall energy-efficiency of wheel loaders. Since wheel loaders are used for a variety of different work tasks, these tasks have to be taken into account when evaluating new powertrain technologies. In order to quantify the potentials to increase the energy-efficiency of these new technologies and to compare them against the state of the art, a universal and reproducible test method is required. Such a method is currently being developed as part of a publicly funded project at the Institute for Machine Elements and Systems Engineering of the RWTH Aachen University.

1 Motivation

The increasing shortage of fossil fuels and the resulting increase in fuel costs, as well as drastically tightened emission laws to reduce global CO2emissions require an increase in the overall efficiency of mobile machinery. To evaluate new technologies in terms of their efficiency enhancement...
