On 10 May 2025, the Institute of Construction and Drive Technology (IKAT) presented itself as part of the Open Day at Chemnitz University of Technology with two interactive formats: the shadow building game and the MUT Lounge.The shadow building game offered visitors the opportunity to playfully test their spatial imagination. The starting point was a…
In the research project FVA 956I ‘Design Method for Internal Knurled Interference Fits’, detailed investigations were undertaken into the static and cyclical transmission behaviour of internal knurling press fits. This shaft-hub connection is characterized by pressing a hardened hub with internal knurling onto an oversized, softer shaft, creating a form-fit and friction-fit contact zone. The…
IKAT presented the latest research results at the shaft-hub-connections working group, consisting of research centres and industry representatives, in Frankfurt am Main. Topics of various positive and frictional shaft-hub connections were presented in the context of their application. The results triggered lively discussions and form the basis for future applications. We would like to thank…
At this year’s SiME Congress, the IKAT presented an innovative machine element: the sensor-integrated key. This novel key is capable of directly measuring the torques acting on it and wirelessly transmitting the data to computers or smartphones. It offers great potential for future applications, particularly as an early warning system for detecting overloads. This development…
The research issues associated with the fatigue strength of multi-axially loaded shaft-hub-connections (WNV) combine two important core topics that are continuously addressed at IKAT. On the one hand, complicated stress states, so-called non-proportional stresses, occur at the point of failure, which can only be evaluated using special strength hypotheses. In addition, tribological influencing variables, such…
At the 13th SAXSIM Conference in Chemnitz, Mr. Muhammedi presented a lecture on „Numerical Investigations into the strength of deep-rolled components under cyclic loads.“ The project, involving three research institutes – IKAT, IMM, and IF – focuses on analyzing the strength of deep-rolled components under cyclic loads through numerical simulations. Mr. Muhammedi explained the methods…
On 1 March 2024, Mr. Maik Zylla successfully defended his diploma thesis in front of an expert examination committee headed by Prof. Hasse. In his thesis ‚Investigation of the joining and torsional behaviour of combined press-fit and form-fit shaft-hub connections using the example of the external knurled press-fit connection‘, useful extension approaches for existing design…
The 10th Symposium „VDI Fachtagung Welle-Nabe-Verbindungen“ (external link) which deals with shaft-hub-connections will take place on 6 & 7 November in Garching near Munich. All topics relating to the wide range of shaft-hub connections will be presented at this conference, with a particular focus on design/dimensioning, strength verification, production and application, as well as current…
