1. Model Calibration of Nonlinear Mechanical Systems Using Multi-Harmonic Frequency Response Functions
Sammanfattning : In industry, linear finite element models are commonly employed to represent global structural behavior. It is crucial that the computational models are able to accurately represent the structures’ behavior. This cannot always be achieved by the use of linear models. LÄS MER
2. Multistage gearboxes : vibration based quality control
Sammanfattning : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. LÄS MER
