In this paper, numerical simulation has been used to predict the noise inside tracked vehicles. To determine the interaction forces between running track system and the chassis hull of a tracked vehicle, a rigid multi-body tracked vehicle mode, which includes the track moving system, was constructed and simulated using ADAMS software. Finite element (FE) and boundary element (BE) models of the chassis hull of a tracked vehicle were created and adopted to perform the vibro-acoustic analysis. Correlation between the FE and BE models and physical measurements proved sufficiently good that the models could be used to predict the interior noise in a tracked vehicle. The structural frequency dynamic response was determined using the software MSC/NASTRAN. The interior noise was predicted using the software SYSNOISE. The predicted noise levels in a tracked vehicle have been found to be in good agreement with physical measurements.
