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.
Description
technical field [0001] The invention relates to a device for testing vehicle noise, in particular to a vehicle tire noise testing system, which mainly tests the noise emitted by tires on different road surfaces. Background technique [0002] With the increase of highway construction and car ownership, people's travel range is getting wider and wider, and people have more and more opportunities on highways. In a car running at high speed, tire noise becomes the main noise source of the car. In the existing test technology, it is mainly used to measure the six-degree-of-freedom motion parameters and their relationship with the six-component force on the ground, and cannot be used for testing and research on tire noise. [0003] Therefore, it is necessary to propose a vehicle tire noise test system, which can test the noise generated by the interaction between the tire and the road surface during driving, so as to study the noise mechanism of different tire materials and tread...
