The master’s thesis addresses the development and modification of an interface that enables the execution of torsion tests on an existing tensile-compression testing rig. The goal was to reduce friction in the contact parts of the mechanism and to improve the accuracy and stability of measurements. To achieve this, flexural bearings were used, structural
modifications of the upper and lower mounts were carried out, and numerical analyses as well as experimental tests were performed. The results showed that the modified interface allows for repeatable and stable measurements, with reduced losses due to friction. The work thus provides a cost-effective alternative to purchasing dedicated torsion testing rigs and opens possibilities for further research and system optimization.
