Publication in the journal Mechanism and Machine Theory
One of the research fields at the Professorship MP is the development of new methods for the design of compliant mechanisms. The continuum-based approaches employed involve formal optimization techniques to synthesize mechanical systems whose function relies on the deformation of elastic areas.
A new method for the topology optimization of selective compliant mechanisms was developed. The formulation of the optimization problem allows to design a compliant mechanism in such a way that it responds to external forces with a predefined, desired kinematics in a load-independent manner. This method has been extended by Ms. Stephanie Kirmse by incremental linearization of the optimization problem, which allows the application of more efficient and stable linear optimization algorithms.
The result of this research has now been published in the renowned journal Mechanism and Machine Theory. In the publication, the novel synthesis method is presented, demonstrated by several numerical examples and eventually verified experimentally. For this purpose, a prototype of one of the presented shape-adaptive examples (see picture) was produced through 3D printing and successfully benchmarked with the numerical results.

Long-standing employee leaves the professorship
Dr.-Ing. Sven Hauschild is leaving the TU Chemnitz after a total of 12 years of affiliation to face new challenges in the economy.
From 2008 to 2013, Mr. Hauschild studied in the Microtechnology/Mechatronics program at the TUC. During this time he was engaged as a research student at the Chair of Machine Elements and was appointed as a research assistant at the end of 2013. His research in the field of fretting corrosion culminated in 2019 in his dissertation on „Frictionally stressed steel contacts – design and evaluation using system-specific fretting corrosion factors“.
For four years, he was head of the „Competence Center Shaft-Hub-Connection“ at the Chair of Machine Elements.
The entire professorship thanks him for his achievements and wishes him all the best and continued professional success in his new (and old) home town of Görlitz.
Start winter semester 20/21
The professorship of Machine Elements and Product Development wishes all students a good start to the lecture period. Despite the current restrictions and difficulties, do not lose sight of your goals in your studies.
In particular, we would like to wish all first-year students a good start to their new phase of life. Stay curious and motivated to master the desired course of study.
Mr. Reiß successfully defends his doctoral thesis
We are pleased to congratulate our former colleague Mr. Reiß for successfully defending his doctoral thesis.
In his dissertation on the subject of „Model test methods for determining real static friction values of joined machine elements“ he dealt with the transferability of static friction values determined in laboratory test methods with simple model samples to real applications. A methodical procedure was developed to ensure the transferability of the results.
We wish Mr. Reiß all the best for his future career!
