Stationary Hydraulic Systems
The research focus „Stationary Hydraulic Systems“ comprises the research and development of hydraulic drive technology and control, as they are mainly used in machines of industrial production. Examples are presses, plastic injection moulding machines, rolling mills and paper machines. The investigation of novel drive concepts such as electro-hydraulic compact drives or the development of energy-efficient cooling concepts in machine tools are also part of this research area. The focus of the research is the methodical development of smart control and circuit technology, which
- increases the productivity, performance and energy effi ciency of the machines,
- shortens and simplifi es the commissioning of machines and processes,
- increases ease-of-use and simplicity of operation,
- minimizes the maintenance eff ort and increases the machine availability,
- integrates modern communication technologies and control topologies (Industry 4.0).
