The master's thesis deals with the development of a load-bearing measuring element for measuring tensile forces of up to 50 kN using strain gauges. The mechanical behaviour of the element was evaluated using the finite element method, which enabled an iterative interactive optimisation of the geometry. The aim of the optimisation was to ensure the required load capacity and sufficient local deformation at the measuring points, which is essential for achieving the desired measuring accuracy. Of the design concepts investigated, the configuration with an elliptical opening reinforced with an additional rib and a locally thinned wall at the measuring point proved to be the most suitable. This design provides an optimal balance between stiffness, deformability and structural robustness and enables accurate and repeatable measurements even under complex loading conditions.
