Inthis paper , a vehicle structural finite element model for an off - road vehicle is optimized under NVH discipline and based on the vibration behavior. Firstly the vehicle structural geomtry and its details are modeled in CATIA software and then meshed in hypermesh soft ware.

DOE method , modal analysis, NVH,frequency map, optimiztion.
