摘要
Abstract
Rough asphalt pavement has a wide application in China's highway construction. In order to reduce the dependence of the outdoor tire noise test on the weather, this paper compares the differences between indoor and outdoor tire noise spectra obtained in the tire noise tests. It is found that all measurement points have a high degree of matching between the indoor and the outdoor test data when the vehicle operating condition is 50 km/h - 20 km/h gliding. Moreover, the frequency band of the matching area is just the typical tire noise frequency range of this pavement. When the vehicle traveling at the uniform speeds of 20 km/h, 30 km/h, 40 km/h and 50 km/h, the wheel noise data still has higher matching degree, while the one of interior noise data is poorly matched. Therefore, when the four-wheel drive drum test is performed on rough asphalt pavement, the right rear wheel data under 50 km/h - 20 km/h gliding condition can be used as a good substitution to match the outdoor test noise data. Thus, the dependence on harsh environments and the cost of the test are reduced and the test safety is improved.关键词
