VDI symposium

VDI symposium
The 8th VDI symposium on shaft-hub connections will take place from 26 to 27 November in Stuttgart. Under the motto "Dimensioning - Production - Applications", the conference offers a suitable platform for innovations as well as the technical exchange between experts and colleagues. The professorship of machine elements and product development, as an expert in the field of shaft-hub connections, will once again contribute to the transfer of knowledge between university research and industry with numerous innovative contributions this year. We are looking forward to an interesting conference and hope to welcome you at our numerous topic-specific conference stands.

Very good contribution to friction coefficient research of Dominik Müller

12.10.​2018

On 11.10.2018 Mr. Müller defended his thesis and was rewarded for his outstanding performance! The work on the topic „Statistical analysis of a standardised test method for determining static friction values“ was able to validate the usage of the standard normal distribution to the test method as expected on the basis of a large random sample (89 tests under the same conditions). The newly introduced methods represent a contribution to highly qualified results, i.e. statistically verified Coefficients of Friction, which are determined with the industrially widely recognised test method. The professorship thanks the young academic for this outstanding achievement and Prof. Götze and Dr. Schmidt of the Chair of Management Accounting and Control for the cooperative support and economic evaluation of the work.

Internal conference in Nature Conservation Centre Schlettau

09.10.​2018

With the aim to “forge” the future of our professorship MP, the research associates leaded by Prof. Hasse met for internal conference near Annaberg-Buchholz. The work was targeted at the promising science topics, which will be pursued in next research period. In connection to the mining tradition of the region of Ore Mountains, the team of the professorship MP visited the museum “Frohnauer Hammer”, which included old water-powered forging technology.

Especially the progress compared to the present-day machines motivates us for further research work.

The team of professorship MP wish a successful and targeted start of new semester.

New employee at the professorship

20.09.​2018

We are pleased to welcome Mr. Silvano Oehme to the professorship by 01.09.2018 as a scientific assistant. As a student, Mr. Oehme has done research at the professorship in the fields of mechanical design in CAD and simulation of rolling bearing migration. In the tribology research group, Mr. Oehme will now work out the development and simulation of wear.

Research

Hydrodynamic/Plain Bearings

Hydrodynamic/Plain Bearings
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).

Shaft-Hub Connections

Shaft-Hub Connections
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.

Friction Corrosion

Friction Corrosion
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.

Flexible Systems

Flexible Systems
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.

Strength of Gearing

Strength of Gearing
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.

Friction coefficients for force-locked Connections

Friction coefficients for force-locked Connections
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.
