FEM simulation and experimental evaluation of a thin walled components dynamic behaviour
Waste cost in most processing and manufacturing operations of thin walled components can be attributed to process vibration. To meet the given tolerances of the part a manufacturing process is required while operating within a relatively close set of process parameters. Due to the constantly changing behaviour of a thin walled component these limits or operating conditions change permanently. To understand the positional influence of a component onto its vibration behaviour two potential activities can be pursued - the time consuming, but more accurate experimental modal analysis or the faster, but possible faulty simulation method. In order to understand if the outcomes of both analysis methods can be used to define an efficient machining strategy that achieves a determined manufacturing integrity, in this paper both methods are compared to each other. Therefore the conformance of both methods is determined, researching the machining position depending on the modal behaviour change of a cantilever beam. The paper closes discussing future prospects of process design and diagnostic strategies to improve the end product's quality.
