Start of summer semester 2019

01.04.​2019

For the beginning of the 2019 summer semester, we wish all students a good start into the semester, curiosity for knowledge, fun at learning and endurance. Don’t lose the focus on why you are studying mechanical engineering. But also enjoy student life and the freedom of studying to the full.

We wish you every success!

New employee at the professorship

06.03.​2019

Since February 1th 2019 the team in the experimental field of the Professorship Machine Elements and Product Development has been strengthened by the appointment of Anika Bahnert. This provides the additional capacity to cope with the expansion and redesign of the test site in the coming months. We are looking forward to a good cooperation and wish much success and creativity.

11th SAXSIM

26.02.​2019
11th SAXSIM

The 11th SAXSIM will take place on 26.03.2019 in the main lecture hall of the Chemnitz University of Technology. The program includes more than 30 lectures, the awarding of the 11th student competition, the popular Mathcad-HandsOn-Workshop as well as for the first time an ANSYS product training and the possibility to visit selected test fields of the Chemnitz University of Technology. Furthermore, there will be numerous interesting lectures on the topic of simulation.

If you are interested, you can register here until March the 15th, 2019.

Research

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.
