Tire/road noise simulation for optimization of the tread pattern

摘要

There are many factors related to the tires, which are important to the level and spectral characteristics of the tire/road noise. The tread pattern is one of the most important factors in this respect. This paper deals with one aspect of the tread influence - namely tread pattern randomization which is a measure used to decrease tonality of the tire/road noise. The first part of the paper gives a short overview and comments on methods of data transformation and optimization, which have been reported in open literature. The next part is dealing with one of the possible approaches in this respect, which has been developed and successfully used by the author in designing numerous tread patterns. Noise spectra for tires having the same tread pattern segments but being differently randomized are presented.
