Mobile & Stationary Systems
The group “Mobile & Stationary Systems” focuses on the systematic, tailored redesign or new development of hydraulic systems and architectures in an increasingly mechatronic environment.
The extension of fluid mechatronic drive structures by modern information technology as part of the IIoT is continuously increasing the scope for R & D projects. The research for stationary systems therefore focuses on
- enhancement of the systems’ durability
- increasing energy efficiency
- extension of maintenance intervals as well as preventive maintenance.
The availability of intelligent components leads to new alternative and robust system concepts. In addition, the wider use of real-time control hardware has resulted in hydraulic-mechanical controllers and controls being progressively replaced by electrical controls. This also applies to the field of mobile systems.
Furthermore innovative drive concepts have to be developed for mobile applications in order to meet the ever increasing demands on availability, fuel efficiency and productivity. A holistic view of the diverse systems in mobile applications from the primary energy source to the output creates fundamentally new drives. Since current machines and processes in the field of mobile hydraulics are still usually controlled by people, the operability and acceptance of new systems have a high priority.
In the framework of research for mobile systems, the following focuses are emerging
- Hybrid drive trains
- Energy recovery systems
- Higher level machine controls
- Human-Machine Interaction
Hybridization of Mobile Machinery
The aim of this research approach is to optimize the load on the diesel engine, which will remain a central component of construction machinery today and in the near future. By recovering energy from the machine’s drives, the power requirement on the diesel engine can be optimized. All in all, fuel consumption and emissions (noise and particles) can be reduced in this way.
Carbon Footprint of Actuators for Industrial Automation Systems
The reduction of greenhouse gas (GHG) emissions necessitates the knowledge of the significant influence factors in automation systems. In cooperation with FIR of RWTH Aachen University, an online based user tool for the estimation of GHG-emissions throughout the life cycle of pneumatic, hydraulic and electromechanical drives in accordance to technical guidelines is developed.
Drivetrains for Renewable Energy
Drive trains are being developed for various forms of renewable energies, including solutions for wind, wave and flying wind turbines. The design goals for drivetrains are high degrees of energy generation ranging from partial to full load, compact design, low life cycle costs and successful competition against electro-mechanical drive solutions.
Machine and Process Controls
Due to the increasing digitalization and the high availability of cross-machine and cross-process data, new system concepts are developed in close cooperation with the group Digitalization & Automation. These in turn lead to great potential for shortening production and cycle times, improving human-machine interaction and process stability.
