Beschreibung

Initial situation

The machining of thin-walled components is particularly challenging due to low structural stiffness and high susceptibility to vibrations. Process instabilities may significantly impair dimensional accuracy, surface quality, and overall process reliability.

 

Thesis aim

The objective of this thesis is to develop a structured concept for predicting component vibrations based on low-fidelity data (e.g., FEM simulations) and high-fidelity data obtained from experimental measurements. As part of the work, a systematic literature review shall be conducted to analyze and assess relevant approaches in the fields of component dynamics, data-driven and hybrid modeling, and data fusion.

Based on this review, a methodological framework for combining both data sources shall be developed, and suitable algorithms for predicting the dynamic behavior of thin-walled components shall be proposed. In addition, potential optimization strategies for machining processes, for example with regard to toolpath planning, machining sequence, or engagement conditions, shall be identified and evaluated.

Voraussetzungen

Requirements

Studies in mechanical engineering, production engineering, aerospace engineering, mechatronics, or a related field; interest in machining, simulation, data analysis, and algorithm development; basic knowledge of Python, MATLAB, FEM, or dynamics is beneficial.
