Energy Effecient Self-contained Hydraulic Drive Concept

The objective for this project is the development of a standalone hydraulic drive concept characterized by being highly energy efficient, scalable, durable as well as commercially attractive and in-line with industrial trends. This is achieved using speed-variable pumps and simple controllable valves in combination with innovative control software, realized through in-depth theoretical and empirical studies for the dominant physical properties, control designs, lifetime tests and extensive empirical knowledge from industrial applications gathered throughout the project period. The goal is a drive concept in-line with industrial trends in terms of electrification and condition monitoring, an average energy efficiency above 70 % and the potential to replace 15 % of Bosch Rexroth A/S' current market and increase market shares in relevant segments by 2.5 percentage points in 2024. Through this the drive concept will constitute a new foundation within hydraulic cylinder drive technology. The ideas and findings of the project are expected to propagate into the remaining part of the fluid power industry, potentially leading to a significant reduction in emissions conventionally seen in this industry segment.
