基于弹性流体动力润滑理论,将轮胎、路表水膜和路面作为一个弹性流体动力润滑系统,研究了轮胎的动力滑水问题。在轮胎上建立坐标系,则轮胎是静止的而水膜是运动的,推导了控制动力滑水的Reynolds方程、水膜厚度方程和变形方程,采用复合直接迭代求解方法,并编制了计算程序,分析了轿车轮胎在沥青路面上行驶的动力滑水。分析结果表明:随着行驶速度的增大,能够引起动力滑水的路表水膜厚度不断减小,当行驶速度为120km.h-1时,路表水膜厚度为2mm就会发生动力滑水。
Based on the theory of elastic fluid dynamic lubrication, the tire, road surface water film and pavement are regarded as an elastic fluid dynamic lubrication system, and the dynamic water skiing problem of the tire is studied. The establishment of a coordinate system on the tire, the tire is stationary and the water film is motion, the Reynolds equation, the water film thickness equation and the deformation equation governing the hydrodynamic wake are deduced, the composite direct iterative method is used, and the calculation program is compiled. The dynamic water skiing on the asphalt pavement is analyzed. The results show that with the increase of traveling speed, the water film thickness of the road surface water table that can cause the power slide watering decreases continuously. When the traveling speed is 120km.h-1, the power slide water.
