The overall design and functional implementation of gear drive test system is introduced

open power test-bed for the noise and vibration test and efficiency test of gear transmission is developed.By using dynamic analysis software and spectrum analysis technique for test data analysis

providing evidence for noise source identification of gear drive

and the objective evaluation on comprehensive performance of gear drives is made

also the process of vibration and noise test for gear drive is formed.After certification application example

the noise and vibration test on the test-bed is feasible.
