Zagorodniy A. The influence of road conditions and constructive parameters of car tyres to level of noise emanation

Object of research. The processes of noise creation when the car tire moves flong the road surface. Purpose of research: is to determine the influence of exploitativ and constructive parameters of car tires to level of their noise emanation. Methods of research: The system analyze, the method of end elements, the mathematical analyze, the stayistic treament of research results. Apparatus: The noise measurer of the first class VSHV-003, the microphone M-101. Theretical and Practical resalts: The theoretical dependences of defining the level car tire noise, when it moves along the road surface, are got. The influence of rosd surface, of exploitative and constructive parameters to noise of car tires is determined, the method of noise lowering is worked out, the method of calculation of car tires noise is perfected. Novelty: The complex measure to assessement of influence of tires from different sources of noise creation is offered. The theoretical dependeces, which allow to estimate the influence of theroad conditions and the exploitative and constructive parameters to tire noise, are got. The theoreticak dependences, which allow to account levels of noise because of interaction of with the road, are received. Degree of inculation: Inculated at the Belotserkovskom tire pant The closed share company "Rosava". Sphere of the use: automobile transport.
