摘要（英）：

The invention discloses a vehicle tire noise testing system which comprises a tire installing and loading device, a tire pavement testing and driving device, a noise testing and analytical processing device and a background noise processing device. The tire installing and loading device is mainly composed of a transverse rod controller, a load hydraulic cylinder, a main cylinder controller and a tested tire. The tire pavement testing and driving device comprises a simulated pavement, a pavement supporting rotary frame, a motor, a frequency converter, a driving belt, a supporting wheel, a thrust bearing, an inner supporting base, an outer supporting base, a sleeve base and a base. The noise testing and analytical processing device is composed of a microphone, a tripod, a data interface box, a data processor and a special tire noise testing system. The background noise processing device comprises a noise-proof shield and a noise absorption wall. The vehicle tire noise testing system is simple and compact in structure, low in device background noise and wide in testing speed range.
