Abstract

This research presents a Load Profile Generator model for non-road mobile machinery, which depicts the most common operational profiles that reflect real-world conditions. This technological bottom-up model enables users to parameterize specific machines for simulation and observe their power demand at the actuator interfaces. The application of the Load Profile Generator covers different non-road mobile machinery categories, such as construction, agriculture, industrial and forestry. In this study, the Load Profile Generator was used to demonstrate common operations of material handler and forest forwarder, which have been validated against real-world data to match the results. The usage of Load Profile Generator aids engineers in evaluation machines performance by developing operation strategies. It opens doors to further systems analysis as it can serve as an interface for energy demand calculations. The model's results are accurate enough to provide a sufficient understanding of a wide range of non-road mobile machinery load profiles as well as insights about alternative fuel and power supply concepts helping in optimising the system simulation.
