Analysis on Vibration NVH of General Mechanical

With awareness of environmental protection is increasing, the government regulations on noise limits have become increasingly stringent, people's requirement for the comfort of general machinery is increasing.The NVH performance of general machinery will be the main trend of the future general machinery competition.With the rapid development of general machinery industry in China, the market competition of general machinery is increasingly fierce and the vibration noise of general mechanical has become a very important project to be evaluated. The Regulatory Requirements Related to the NVHThe national compulsory standards related to NVH performance is GB1495-2002-general machinery noise outside the vehicle acceleration with performance requirements.According to the
