考虑胎体复杂变形的轮胎非稳态侧偏特性理论模型 总被引:14,自引:1,他引:14
本文从肥体的一般变形模式出发,根据胎体的侧向弯曲变形及扭转变形计算出胎面的侧向瞬时变形,从而建立了小幅运动时轮胎非稳态侧偏特性理论模型。考虑胎体的复杂变形之后,模型能真实地反映轮台力学特性和物理实质。 相似文献

ABSTRACTTires are used by the customers during several tens of thousands of kilometres, and before their replacement, the driver will encounter a continuous variation of tread depth due to the tire wearing. Although the wet braking labelling demonstrates the performance of the tire in the new stage, it is known that the wet traction evolves with tire wear. In this paper, an in-depth comparison of the wet grip performance of new and worn tires will be conducted, based on the regulatory wet braking test. For this purpose, we propose an original approach to analyse braking test results, which allows breaking down and quantifying the relative importance of the mechanisms involved during this test. This study demonstrates that two main mechanisms are taking place during the entire test: rubber friction and hydroplaning mechanisms. The µ value obtained at low speeds reflects the friction potential of the tested tires while the decline of performance at higher speeds is attributed to hydroplaning mechanisms. This analysis is conducted on numerous tires and demonstrates that current regulatory test applied on new tires is focussing mainly on the rubber friction mechanism. The same test applied on worn tires exhibits both rubber friction and hydroplaning mechanisms. The mechanisms decomposition shows that the source of the performance decline from new to worn status varies greatly, some tires having most of their performance loss due to hydroplaning, some others due to rubber friction drop. 相似文献
