Experimental Research On Vibration And Noise Mechanism Of Swing Machine

As a kind of oxiding exercising appliance,the swing machine is designed for those who rest indoor of the machine. Its noises can arrive at 56dB when working. .For such a special condition ,it is impossible for users to bear so high noises. So it's necessary to take the equivalent measures to decrease the vibration and noise by researching and analyzing the swing machine.The paper summarily introduces the developing state of the vibration and noises and some theories about decreasing the vibration and lower the noises. By analyzing the structure of the swing machine, finds out the vibration's sources and its spreading path,tests the sound intensity of the original machine, then identifies and orientates the sound sources to find the advantage frequency of the vibration; analyzing the frequcecy spectrum and model test the paper sets up the main models of vibration of the sound travel, finally by taking some measures and through experimenets find out improved method of decreasing the vibration and loweringnoises.
