Employee leaves professorship

After many years of active cooperation at the professorship Machine Elements and Product Development Mr. Schiemann leaves us. The successors trained by him follow in great footprints and take over the tasks in the areas of rolling bearing creeping and tribology. At the farewell party, many memorable moments of the past years were evaluated once again with cakes and barbecue food.

We thank Mr. Schiemann for his support and wish him all the best for the future.

Extension of the test site

With the relocation of the machine bed with three electric motors and two testing fixtures, the first step towards the expansion of the test site of the professorship was taken. With combined forces, the machine bed found its place at the new location. The testing devices use resonance excitation to transfer dynamic loads to shaft-hub connections (SHC) and thus enable state-of-the-art tests to be carried out on SHC. Furthermore, the machines offer great potential for investigations of the vibration behaviour of dynamically rotating systems. The motors and testing devices thus provide an increase in capacity and quality for experimental research at the Competence Center Shaft-Hub Connections.

Hiking Day 2019

Shortly after the Easter holidays, the members of the professorship took advantage of the continuing beautiful weather for the annual hiking day. The start was in Radebeul. From there we took the Lößnitzgrundbahn, an ancient steam train, to Moritzburg. After a short rest and visit of the castle we hiked back to Radebeul. In addition to many enjoyable personal conversations, the technical discussions did not come too short.

New members in the MP team!

We are looking forward to the immediate participation of Mrs. Kirmse and Mr. Friedrich in the research and teaching tasks at the MP professorship. In a DFG research project, Ms. Kirmse is focusing on compliant systems, continuing the topic of her master’s thesis in basic research-oriented studies. Mr. Friedrich complements the expanding research group „Plain Bearings“ and will investigate on the influences of combined axial and radial bearings.

We wish the two newcomers all the best in their work at the Institute.


Growing ecological and economic pressure leads to ever higher and more complex stresses in the development of plain bearings. The research at the institute is therefore primarily concerned with the investigation and development of alternative sliding materials and the influence of geometric deviations. The main focus of the investigations is the wear behaviour under the most varied operating conditions (particles, mixed friction, hydrodynamics).
The permissible loads of selected WNV (tapered and cylindrical interference fit as well as feather key, knurled, polygonal joints, etc.) have been investigated primarily at IKAT for decades in the area of fatigue, fatigue and fatigue strength. The behaviour under individual loads (bending, torsion) as well as combined dynamic loads is analysed.
In contact with various components, deformations in connection with the prevailing joint pressure initiate the damage process of friction fatigue (friction corrosion). Current research activities at the institute focus on basic research on the damage phenomenon of friction corrosion and pursue the objective of developing an impact-compliant calculation method.
While conventional mechanisms owe their deformability to the sliding or rolling interfaces in the joints, flexible mechanisms fulfill their function through elastic stretches in places that are deliberately designed to be flexible during design. This functional principle enables novel, shape-adaptive structures, which can be used, for example, in softrobotics or in variable-shape wings. The professorship focuses its research on optimization-based synthesis methods.
The strength tests focus on the tooth root load-bearing capacity of worm gear units. The challenge to numerical imaging lies in the complex geometry and the special material bronze.
The coefficient of static friction (also: coefficient of friction or coefficient of friction) is to be understood as a system variable with a multitude of influencing parameters. In order to use existing potentials in friction-locking connections (e.g. screw, flange, press-fit connections), an experimental investigation is indispensable. With the help of standardized test methods on model samples, a wide variety of tribological configurations are examined at the research centre with regard to their transmission behavior. A major field of research is the synthesis of new design/selection tools for friction-enhancing measures (e.g. micro/laser structures, hard particles, coatings) for static and dynamic load cases.
