Working Group 2 :
Tasks c, d and e:
This WG will focus on
the development of experimental NVH analysis techniques. Both interior
and
exterior sound aspects will be studied together with the coupling of ICE with electric devices.
Experimental techniques such as Experimental Modal Analysis (EMA), Operational Modal Analysis
(OMA) and Operational Deflection Shape (ODS) will be combined in order to identify the NVH issues
in the low, mid and high frequency ranges. The WG will be composed of two Subgroups for the
different experimental items: (one for interior issues: structural aspects, excitations and
resonance identification; a second one for exterior aspects like warning sound definition).
exterior sound aspects will be studied together with the coupling of ICE with electric devices.
