Abstract :
This paper introduces unusual vibration and noise test of the transmission in NVH road testing system. It analyses test data in detail by using dynamic signal analysis software. By analysis, we know that the vibration signal and noise signal measured in road testing system exactly match the actual vibration and noise signal of the transmission, which shows that it is feasible to carry on vibration and noise test (NVH test) in this system.
