Study on Vibration and Noise Test for Gearbox

LI Run-fang,LIN Teng-jiao,TAO Ze-guang (State Key Laboratory of Mechanical Transmission,Chongqing University,Chongqing 400030,China)  
The experimental model analyses method is appli ed to test the natural c haracter in order to obtain precision model parameters and to modify the 3-D FE M model for dynamic analyses.The vibration acceleration at 110 test points on 5 m easurement surfaces are measured and the time history of acceleration,velocity a nd displacement a s well as acceleration frequency spectrum on all test points are acquired by tre atment in FFT analyzer.At the same time the sound intensity on 416 test points a re measured to gain 3-D sound intensity distribution chart on 5 surfaces.The te st results are almost in line with the numerical results.
