Improved Techniques for Uniaxial and Multiaxial Vibration Test Profile Definition
This work aims to improve profile derivation methods for uniaxial and multiaxial vibration testing. Thereby, the focus is put on the inclusion and processing of phase information between the excitation axes. An inherent necessity is the availability of field data. Two existing methods are independently extended by additional phase information and an appropriate processing. The first method is the Fatigue Damage Spectrum for a uniaxial profile derivation. The second method is the enveloping technique for a multiaxial profile derivation. Both methods are theoretically discussed and then evaluated with a fatigue damage calculation of an exemplary structure.Abstract
