滑水及抗滑力的衰减是潮湿条件下影响道路及机场跑道交通安全的两个重要因素。模拟潮湿路面抗滑力是一个相对复杂的问题。笔者采用理论研究方法,提出了一个分析计算模型,用来模拟车轮滑移速度增加时,潮湿路面的滑水现象及抗滑力的衰减情况。该理论公式及三维有限元模型的理论基础是固体力学及流体动力学。通过NASA滑水速度方程,对模型计算的滑水速度进行分析验证。
Water skiing and anti-slippery force attenuation are two important factors affecting the traffic safety of roads and runways in wet conditions. To simulate the slip resistance of wet pavement is a relatively complicated problem. The author adopts the theoretical research method and puts forward an analysis and calculation model to simulate the phenomenon of water sliding on wet pavement and anti-sliding force attenuation when the wheel slip speed increases. The theoretical basis of the theoretical formula and the three-dimensional finite element model are solid mechanics and fluid dynamics. The speed of water skiing calculated by the model is verified by NASA water speed equations.
