| Summary: | The dynamic characterisation of vehicle structures is a crucial step in
NVH analysis and helps in refining the vibration and noise in new vehicles,
which is becoming a marketing edge as well. This paper investigates the
dynamic properties of two parts of the vehicle structure which are door and
hood panels. Theoretical modal analysis, which is referred to as finite element
analysis (FEA) and experimental modal analysis (EMA) or modal testing, has
been used as investigative tools. The paper investigates the structural dynamic
properties of door and hood panels of a local car. ME’scpe software was used
to analyse the data obtained from the Pulse to extract the dynamic properties of
the panels. Ls-dyna software was used to analyse the dynamic behaviour of the
structure. The comparison between the results obtained from both analyses
showed some similarity in frequencies and mode shapes. Finally the paper
concludes that experimental modal analysis and finite element analysis can
both be used to extract dynamic properties of structures. |
