Tire pattern noise simulation using aerodynamic mechanism

摘要

The present invention relates to a tire pattern noise reduction method considering the host resonated note. This The purpose of the invention, there is provided a tire pattern noise reduction method considering the host resonated note to provide a pattern that can be produced through the pitch noise Thai designed to reduce the number of tire noise level of the actual running vehicle. the method of the present invention for achieving the above object effective measure ground plane (Foot print) of the tire and, calculating the ground the leading end (Leading Edge), and the length of the ground plane of the tire, and measuring tire dimensions and calculating a longitudinal groove length, and calculating a host resonated note frequencies; Calculating the total number of pitches and tire and generate a basic pitch arrangement and the pitch pattern shape and generates the application data with the frequency of the pitch pattern and the data thus obtained a fast Fourier transform (Fast Fourier Transform) and the fast Fourier transformed data summed to generate a frequency waveform by summing the calculated host resonated note frequency and pattern of the tire noise reduction method proposed considering the host resonated note, characterized in that by evaluating the noise levels including the step of developing a low noise pattern.
