Thesis Student: Integration of Modal Analysis in the Context of Dimensional Accuracy Problems

Life is always about becoming... In life it is about going on a journey to become the best version of our future self. As we discover new things, we face challenges, master them and grow beyond us.

Apply to Mercedes-Benz and find the area where you can develop your talents individually. You will be supported by visionary colleagues who share your pioneering spirit. Joining us means becoming part of a global team whose goal is to build the most desirable cars in the world. Together for excellence.

Number: MER0003ZI8 Within the Mercedes-Benz car development, our department is responsible, among other things, for the development of tolerance concepts in raw construction and for conformation. We are looking for a reinforcement in the team tolerance management with a focus on tolerance simulation. You accompany the development process of sophisticated Mercedes-Benz raw structures and conformation components from the design to the series. Imagine the global challenge and work closely connected with development hubs on different continents. These challenges include: In the production of components in a plant, deviations from the desired geometry occur due to the process

By tolerances, it is ensured that these components can be joined together in the further process so that the resulting assembly can fulfill the desired function.

To determine tolerances, 3D-CAD supported simulation tools are used nowadays - this makes it possible to simulate, for example, the assembly process in body blank construction with the component scatters occurring

Thus, statements on the distribution of joints and offset measurements as well as functional dimensions can be given taking into account the assumed individual part deviation in the series process.

In the preparation of such simulation models, certain requirements must be complied with - these specifications are available in the specialist field with the aid of expert knowledge

Within the scope of this activity, the modal analysis in the context of dimensional accuracy problems is to be integrated into existing processes, taking into account the current state of the art and the internal development processes. The existing process and the existing data structures with associated interfaces should first be analyzed. In addition, various components are to be examined with the numerical modal analysis and the possible integration into the existing processes is to be demonstrated. Finally, the findings will be transferred to a proposal for use in the existing development process. The activity can begin from April 2026. The final topics will be discussed with the university, you and us.

You are about to complete your master's degree in mechanical engineering, production technology, vehicle technology, or a comparable study direction

You have a high interest / previous knowledge in the field of FE simulations, modal analysis, statistical tolerance simulation, programming (ideally Matlab or Python), as well as in the field of product development

High self-employment and self-initiative

Objective and analytical methods are of course for you

You own team and communication skills

You have well-founded knowledge of German and/or English in word and writing
