Vehicle interior noise testing road surface, laying method of vehicle interior noise testing road surface, and vehicle interior noise testing method
The invention provides a vehicle interior noise testing road surface, a laying method of the vehicle interior noise testing road surface and a vehicle interior noise testing method. The vehicle interior noise testing road surface comprises a surface layer of which the thickness is 120mm, wherein the surface layer comprises stone materials mixed at a weight ratio of 1:1; the particle sizes of the stone materials are 10mm and 15mm respectively; and gaps between the stone materials are filled with modified asphalt. According to the invention, road surface parameters of a rough road surface are designed and determined; the testing road surface is added and perfected; through a test of vehicle interior noise on the rough road surface, a testing and evaluation scheme is provided for vehicle interior noise reduction; the NVH (Noise Vibration and Harshness) level of a finished automobile is raised; and the product performance is more competitive.
