- Abstract:
- Atthe design stage considering its NVHperformanceof thebody，comprehensiveuse of multi-body dynamicsandacoustic solid couplingFEMofthe carbody prediction simulation of interior noise．C level pavement file is establishedby Matilab／Simlink，Multi-body dynamics model is set up and carry onthe simulation byMSC．Adams／Car，Interior noise simulation predictions of a minibus’fluid-solid coupling model which caused by Pavementincentives with MSC．Nastran，through the analysis of the evaluation to the simulation resuhs reachedNVHperformance prediction at the design stage of body，provide a reference data for car body design through the evaluation analysis of simulation，and compared with real vehicle measurement result，the SPLdistribution trend of measurement point is consistent，shows the feasibility of this method in engineering practice．
