A method for predicting tire pattern noise

Abstract

The application provides a tire pattern noise prediction method, which solves the technical problems of long test period, high cost, and many uncertain factors in the existing tire through noise test chamber outdoor experiment, and the steps mainly comprise: according to the test tire parameters, matching and installing the tire and the rim on the bench dynamometer test machine in the semi-anechoic chamber; arranging the microphone around the contact center between the tire and the road surface according to the set position to receive the noise signal generated by the interaction between the tire pattern and the road surface; and obtaining the effective noise value by calculating the indoor test data through the establishment of the indoor and outdoor correlated mathematical model. The application simulates the relatively close real vehicle road test by loading and testing the single tire on the test bench, collects data by cooperating with the array sound sensor, restores the relatively close outdoor test result by combining the algorithm, and on the basis of the effective data, not only saves the overall test cost, but also improves the test efficiency, and can be widely applied to the tire test technical field.
