Prediction of Tire Pattern Noise
نویسندگان
چکیده
The characteristics of tire/road interaction noise are mainly determined by the tread pattern of a tire and it is known that the impact force at leading edge of tire is the main cause of the pattern noise. This study is concerned with the prediction of tire pattern noise: The procedure involves the measurement of the impact force at leading edge, the employment of Hertzian impact theory and longitudinal quadrupole model, and the measurement of transmission characteristics between car interior and exterior. Predicted pattern noise was compared with measured exterior and interior noise of a car driven by the chassis dynamometer in a semi-anechoic chamber. It was observed that they agree reasonably well.

متن کاملModeling and Experimental Verification of Vibration and Noise Caused by the Cavity Modes of a Rolling Tire Under Static Loading
Tire cavity noise refers to the vehicle noise due to the excitation of the acoustic mode of a tire air cavity. Although two lowest acoustic modes are found to be sufficient to characterize the cavity dynamics, the dynamical response of these two modes is complicated by two major factors. First, the tire cavity geometry is affected by the static load applied to the tire due to vehicle weight. Se...

The road transportation sector places a severe burden on large parts of the population in the form of road traffic noise. A main contributor to this is the rolling noise generated by the tires of trucks and other heavy vehicles. Advanced simulation tools are not only needed for a better physical understanding of rolling noise generation, but also for the design of quieter tires and road surface...
متن کاملThermal Analysis of Tire
One of the great enemies of rubber compounds is heat. Heat will cause chemical and physical degradation of vulcanized rubber as well as a considerable loss in its strength. A major source of heat generation in a tire is due to internal friction resulting from the viscoelastic deformation of the tire as it rolls along the road. Another source of heat generation in a tire is due to its contact fr...
