The invention relates to a method for matching a power 
system and a drive 
system based on vibration performance. The method includes the steps that the 
rigid body mode of the power 
system, the drive system, the main speed reducing ratio and the mode of a rear axle system are matched reasonably, the 
rigid body mode of the power system cannot stimulate the drive system mode, and the exciting 
force frequency below the main speed reducing ratio cannot stimulate the mode of the rear axle system. The method is mainly and specifically used for automobile 
model development at the earlier stage. Due to the fact that a practical entire automobile does not exist in entire automobile development, checking can only be achieved through 
simulation, CAE simulated analysis is conducted on the power system and the drive system, a mode distribution table is planned, the power system and the drive system are matched reasonably, and the phenomena that the 
rigid body mode of the power system stimulates the drive system mode, and the exciting 
force frequency below the main speed reducing ratio stimulates the mode of the rear axle system so that 
resonance can happen are avoided. The entire automobile NVH performance is improved, the development cycle is shortened, and the development cost of an automobile is lowered.
