The range of applications for dry-running clutches and brakes is considerable. They can be found in conveyor systems and technology, machine tools, cranes and lifting applications, automation technology and medical technology. In the future, sports cars with electrified powertrains will have to have transmissions with shiftable clutches to achieve "optimum acceleration" as well as "high top speed". The latest developments in the automotive sector, such as the clutch-by-wire system, open up efficiency gains in the powertrain. But the field of application covers much more, with dry-running friction systems providing reliable deceleration for high-speed trains in the form of pneumatic braking systems. In everyday applications such as elevator systems, lift systems, etc., dry-running clutches and brakes ensure the safety of millions of people transported worldwide every day.

Task: In order to test and validate the systems for their subsequent use, friction couplings often have to be loaded to their performance limits. These tests with large energy input into the test system involve high temperatures. Often, several tests are performed with the same system during these test series. The cooling phases can take a particularly long time. A circumstance that makes a prediction of the test duration very difficult. A calculation model is therefore needed to determine expected cooling curve progressions.
