Fig. 16 Amplitude per static
extension of mass
m 1 (A 1 /x st1 ) in function of
ω g /ω 1
Fig. 17 Phase shift between
the excitation force and the
displacement of mass m 1 in
function of ω g /ω 1
5 Simulation Process
In order to reduce the number of the measurements different simulation softwares
may be used. The Autodesk Inventor is available at the Faculty of Engineering
and it has a moderate finite element analysis module (stress-analysis, displacementanalysis, modal-analysis), but it has neither Frequency Response Function (FRF),
nor non-linear material features. The initial tests with ANSYS are encouraging, but
