Vehicle vibration-sound coherence test system and device

The utility model discloses a vehicle vibration-sound coherence test system and device. The vehicle vibration-sound coherence test system comprises a vibration exciter, a vibration-sound signal collector and a processor. And the vibration exciter is used for generating excitation force so as to excite. The vehicle vibrates to generate a vibration signal and a sound signal; the vibration-sound signal collector is used for collecting vibration signals and sound signals and sending the vibration signals and the sound signals to the processor; and the processor performs data processing according to the vibration signal and the sound signal to obtain a coherence result. By adopting the vehicle vibration-sound coherence test system, the vibration exciter excites the vehicle to vibrate to generate the vibration signal and the sound signal, so that the uncertainty of the road surface, the vehicle speed and the like can be avoided and the operability can be improved when the coherence result is tested.
