NOISE SOURCE IDENTIFICATION OF CROSS-BAR TIRE FOR HEAVY DUTY TRUCK/BUS ON A DRUM MACHINE

The velocity dependency of noise was studied for the cross-bar tire first. In the case of 10.00-20 bias-ply tire, about 440 Hz and vicinity was the dominant component for A-weighted overall level. Then the acoustic intensity method was applied for noise source identification. One of the major sources was pinpointed as being the tire sidewalls just above the contact patch. It appears that the dominant noise generation mechanism for the cross-bar tire is the sidewall resonance with the tread vibration caused by the lug blocks.
