TRUCK NOISE VII-A. EXPERIMENTAL INVESTIGATION OF TRUCK TIRE SOUND AND VIBRATION
The report describes the procedure, instrumentation, and data analysis used to telemeter, record, and analyze truck tire sound and vibration. The tire sound signal was monitored at a point approximately one foot to the rear of the tire and was recorded simultaneously with the telemetered tire sidewall vibration signal. Thirteen 10:00-20 bias-ply, tube-type truck tires were evaluated. The data for the tires tested are cataloged and presented here through level, time domain, and frequency domain analyses. The parameters investigated include: speed, wear, load, tread pattern, and pavement texture. The data presented show the relationship of tire vibration to the sound generated. Analyses show nearly a one-to-one correspondence in the changes in levels of both vibration and sound signals under the conditions investigated.
