IKAT welcomes new staff member for the shaft-hub-connections/fatigue division
IKAT welcomes Dipl.-Ing. Maik Zylla as a new member of staff. Following his apprenticeship as an industrial mechanic and further education as a state-certified technician for mechatronics, he completed his degree in mechanical engineering at our university at the beginning of this year. During his studies, Mr Zylla specialised in design engineering and product development, worked for three years as a student trainee in the development department at thyssenkrupp Dynamic Components GmbH and wrote his thesis on the topic of „external knurling press fit“. In addition to his technical expertise, he is interested in cycling, hiking, fitness training and 3D printing. Welcome to the team, Mr Zylla!

Topology optimization of a compliant mechanism
Here you can see the topology optimisation of a shape-adaptive compliant mechanism. Compliant mechanisms are characterised by the fact that they generate desired deformations through elastic distortions.
The starting point for the design is a design space filled with finite elements.
A topology optimisation approach developed at IKAT scales the stiffness of the finite elements in such a way that a structure is created which, due to its stiffness properties, can generate the desired deformation under essentially any load. We refer to such compliant mechanisms as compliant mechanisms with selective compliance.
The desired deformation was defined here as the free surface deforming in the form of a sinusoidal curve under arbitrary forces. The optimisation algorithm designs the structure in such a way that it can fulfil this function well.
We show that a sinusoidal deformation can actually be achieved regardless of the force applied by loading the structure with arbitrary forces.
13th SAXSIM Conference: New insights into the strength of deep-rolled components presented
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 used and presented the conclusions drawn from the simulation results. The collaboration between these research institutes underscores the strength of interdisciplinary cooperation in research.
The insights presented are expected to form the basis for further research in this area.
