The Simulation Analysis And Demonstration System Of Road/Tire Coupled Noise

This issue cooperates with the Hangzhou Zhongce Rubber Group and the Beijing Road Test Institute. Combination of the actual project needs, we find a reasonable way of noise reduction from tire/road noise prediction models and the development of road/tire pattern noise simulation analysis and optimization software.This article stats the Vocal mechanism of road noise from the front, the central and the back and improve the tire/road noise prediction models. Analysis several major factors on the impact of road/tire noise. In addition, introduced two methods to test road/tire noise.In conclusion, summed up the principles, the methods, the mechanism and the optimization of road/tire noise reduction.In an article noise reduction optimization is the kernel and difficult points of road and tread pattern noise control.. This article gives the optimization from the road/tread patterns. In the previous study the majority of articles are only presented a single through improved tire tread to get low-noise tire. This article describes not only the low-noise tread patterns of the optimization method, combined with a low-noise road surface and tire/road noise prediction models introduce the optimization of road/tire noise. The study of low-noise road and tread patterns is based on the parameter.To optimize the parameters of road/tire, which enables the optimization process to become more reasonable and more rapid.This paper improved the tire/road noise prediction models, Created the tire/road noise simulation and forecast demostration system software. give the method to reduce road/tire noise providing high effective approach for lower noise tire designing and production.
