Abstract: This paper analyzes and optimizes the interior noise caused by the mode of electric drive axle of an extended range vehicle by the combination method of test and simulation.By increasing the mode frequency of the electric drive axle to avoid the vehicle sensitive frequency,which the purpose of improving the interior noise is achieved.
Key words: electric drive axle; noise optimization; modal combination
