不同花纹轮胎水滑特性分析

以205/55R16子午线轮胎为研究对象，选用Abaqus软件建立轮胎有限元模型，采用先隐式后显式的方法对5种花纹轮胎进行水滑特性分析。结果表明：基于欧拉-拉格朗日方法（CEL）的轮胎滚动模型可实现轮胎花纹排水的流-固耦合仿真，可较好地预测轮胎行驶时的水流印痕；5种花纹轮胎排水能力由大到小的顺序为纵向沟槽花纹轮胎、正向V形花纹轮胎、反向V形花纹轮胎、纵向S形花纹轮胎、横向S形花纹轮胎；随着轮胎行驶速度的增大，轮胎与路面的接触区从完全接触区向完全上浮区转变。;Taking 205/55R16 radial tire as the research object，the finite element model of tire was established by using Abaqus software，and the hydroplaning characteristics of five pattern tires were analyzed by using the implicit first and explicit later method.The results showed that the tire rolling model based on the CEL method could achieve the fluid-solid coupling simulation of tire pattern drainage，and also could well predict the water flow prints when the tires were rolling.The order of drainage capacity of five pattern tread tires was longitudinal groove pattern tire，normal V-pattern tire，reverse V-pattern tire，longitudinal S-pattern tire and transverse S-pattern tire.With the increase of tire driving speed，the contact area between tire and road changed from full contact area to full hydroplaning area
