| description | Calculation of resonance frequencies of a six-wheeled vehicle has been proposed in this work by means of
computational and experimental methods. In modelling vehicle, elastic body and rigid body tecniques were used
in computational methods. Therefore a three – dimensional finite element model was generated using beam
elements and shell elements. The components of the experiment vehicle such as gas tank, main engine etc. have
been modelled as lumped masses on original location at experiment vehicle. The other approache in modelling
of vehicle is discrete mass model as rigid body. Tires were modelled as spring and dashpot elements.
Impulse excitation using a hammer as well as the excitation with an electrodynamic shaker driven by a
sinusoidal signal were used to measure the frequency response of the system. Vibration measurements were
taken from several places (driver seat location etc.) by B&K 2515 vibration analyser. Finally, the results
obtained from experiment were compared with the calculated results and a good agreement between these
results were obtained. Dynamic absorber was applied to vehicle for removing the hopping frequency in 5-7 Hz. |
