| 摘 要： | 作者利用自己实测的轮胎接地压力分布,用三维有限元方法分析了轻型货车不同轮胎,在不同胎压和不同负荷作用下,沥青路面结构层的力学响应。结果表明:实际的轮胎接地压力分布具有明显的非均匀性,且随轮胎的结构类型、花纹、胎压、负荷甚至使用年限的不同而有很大的差异。轻型货车对路面结构产生的应力响应不能忽视。

| Abstract: | Currently, it is very different from actual condition, in the most research and calculation of pavement mechanics, that mode of tire ground pressure is assumed, especially when it is simplified as circular and uniform load. In this paper, the mechanics response of asphalt pavement under different tire type of light vehicle with different air pressure and loads were calculated using the measured date by the author. Results of this study show that the tire ground pressure is non-uniform distribution obviously which is different with the different of tire type, tire texture, tire air pressure, tire load, and age of tire and that the stress response caused by the difference should not be neglected. |
