Professorship Machine Elements and Product Development


Attandance at International Mechanical Engineering Congress and Exposition


Some days ago, Mr. Ebermann had the honor to present his research results at the International Mechanical Engineering Congress and Exposition (IMECE), ASME’s largest research and development conference counting more than 2400 referees. In front of the professional audience, he succesfully presented his lecture with the topic „Influence of Geometric Shape Defects on Operating Parameters in Cylindrical Journal Bearings“.
For every researchers, such international experience improves the research quality by exchanging the knowledge with worldwide leading professionals.

IKAT conference contribution at the Dresdner Maschinenelemente Kolloquium (DMK)


On 26 and 27 November 2019, the Dresdner Maschinenelemente Kolloquium (DMK) will be held at the Kempinski Hotel Taschenbergpalais in Dresden, now for the ninth time since 2003. The programme includes interesting scientific lectures on the latest research results and practical contributions from industrial applications in the fields of mechanical engineering, plant construction and vehicle construction, with particular attention to drive technology.

Our research assistant Mr. Dipl.-Ing. Christian Günther will be represented with a lecture on the topic „Investigation of the fatigue strength of highly stressed hollow shaft press-fit connections“ and will present practice-relevant results from the IGF project 19149 BR of the research association Forschungskuratorium Maschinenbau e.V. (FKM).

The detailed conference programme as well as the registration documents are available for interested parties to download under this link.

SAXSIM Student Competition


The SAXSIM Saxon Simulation Meeting will take place on March 24, 2020. Besides interesting lectures, the 12th CAD/CAE student competition will take place. The best placed will receive a prize money of 500,- € for the 1st place, 300,- € for the 2nd as well as 200,- € for the 3rd place. The first 10 places will be awarded with either a PTC Creo or a PTC Mathcad Prime student license. In addition, each participant receives a SAXSIM participant certificate.

So don’t hesitate and join in! Further information can be found here.

New member of staff to support the Fretting Fatigue research group


The further development of the professorship in connection with sharpening the focus of research is progressing. Mr. Knabner joined the team of the professorship to strengthen the research group on fretting fatigue, also known as friction corrosion or friction fatigue. After successfully completing his studies, he was now looking for new challenges. Over the next few years he will focus intensively on the phenomenon of strength reduction through friction loading and the influences of prestressing and slip amplitude. The whole team is looking forward to his cooperation and will support him as much as possible.


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.
