| 摘 要： | 根据11.00R20-16PR型全钢子午线轮胎实际结构,考虑轮胎材料、几何及接触非线性,利用ABAQUS有限元软件建立轮胎与刚性路面接触三维模型,并与轮胎径向刚度试验结果对比验证了该模型的有效性;分析了静止竖向荷载作用下胎压一定荷载不同和荷载一定胎压不同的轮胎路面接触应力及印迹分布变化。研究结果表明:轮胎与路面接触应力呈非均匀分布,且接触面积并非路面设计中所采用的圆形而更接近于矩形。

| Abstract: | In this paper,the subject is the actual structure of the all steel radial tire--11.00R20-16PR tire.First,Tire material,geometry and contact nonlinearity are considered to develop a 2D structure tire model.Then the 2D structure is rotated into three dimensional structure by the finite element software ABAQUS and then a 3D model of tire and rigid pavement is established in the static vertical load,analyzing the changes of tire/road contact stress and patch distribution in different tire pressure and load,at the same time,The relationship between the tire longitudinal stress and the tire slip under longitudinal slip steady-state rolling conditions is also obtained.The results show that the tire/road contact patch is not the circle adopted by pavement structure design,but is more approximately the rectangle. |
