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.

On the 20th of December 2018 Dr.-Ing. Mario Schierz successfully defended his dissertation. His topic „Increasing the elastic potential of press connections by plastic conditioning of the joining partners“ sets new standards in the field of designing highly stressed shaft-hub connections. The available calculation method allows for the first time a targeted plastic conditioning of these machine elements to increase their elastic transferability. In the lively discussion, Dr. Schierz was able to convincingly demonstrate that he has undoubtedly achieved this goal in the case of the investigated press connections. In the subsequent evening event, the discussions were then continued until deep into the night, with the technical diction increasingly being modulated.

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.
