Mechanical Engineering

In mechanical engineering, clamping systems are typically implemented with mechanical holders, which can be particularly unwieldy for complex or delicate components.


An alternative solution is provided by fixing systems based on magnetorheological fluids. These systems enable the secure and straightforward attachment of components of any shape by pressing the component into a cushion and fixing it evenly over a large area.

Another area of application for magnetorheological technology is the modification of valve shapes using magnetorheological elastomers in an external magnetic field. This allows valves to adjust the flow of liquids quickly and continuously, representing a significant advantage in a variety of industrial and commercial settings.

Dielectric elastomer foils offer an intriguing opportunity to leverage the flow energy of small streams for unconventional small hydroelectric power stations. These power stations function without transverse structures and do not generate any noise, making them an attractive option for a range of applications.

A magnetorheological fluid (MRF) can also largely or completely enclose an irregularly shaped object. When applying a magnetic field to the MRF, the object is thereby fixed over a large area.

The radial deformation of MRE rings in a radially oriented magnetic field can be continuously controlled by the current of the magnetic coil, i. e. the radial gap between MRE ring and magnetic yoke can be closed continuously and opened again. This creates the characteristic of a proportional valve.

Innovative solutions and developments from research are needed to increase the proportion of renewable energy supply. With the DEGREEN project, funded by the Bavarian Ministry of Economic Affairs, the Fraunhofer ISC has embarked on new ways of utilising renewable energies.
