Title: Method of simulating tire tread noise and apparatus
Inventor: PARKER DAVID H
IPC: G01M17/02
Filed: 1988-02-09
Granted: 1994-11-08
Abstract: A method is disclosed for evaluating the level of objectionable noise associated with the operation of a tire by virtue of its tread contacting a road surface, which comprises digitizing the tread de-sign on a coordinate system so as to define load-supporting portions of the tread in contact with the pavement, and distinguish them in binary form from those portions of the tread which are not in con-tact. as multiple matrix elements; defining a generally arcuate pro-file of a leading or trailing edge of a footprint of the tread by fitting an equation to the edge; sequentially performing the time ensemble summation, of the noise produced by each matrix element, over ev-ery matrix element on the entire circumferential surface: converting the sequence of summations to a periodic analog signal: converting the analog signal to a sound; and, aurally evaluating the sound. In a simplified case 0's and 1's along at least one footprint edge are sequentially summed around the circumference of the tire. The system requires only a means for digitizing the tread pattern. a computer to perform the necessary manipulations of data. and a means to convert a digital signal to an analog signal.
