【摘要】 应用流体力学和动量定理建立了水滑坡面上的行驶临界速度理论公式,介绍了子午线轮胎-水膜-坡面的有限元建模过程。通过对比水平地面和一定倾斜度路面的轮胎接地变形规律,分析了水滑路面上轮胎的爬坡性能,得出了轮胎载荷与倾角的关系。同时比较了倾斜角α=3°和α=8°时随行驶速度的增大轮胎与地面接触力的变化过程,并预估了坡面上的水滑临界速度。更多还原

【Abstract】 Application of the Hydromechanics and the Momentum theorem,the driving critical velocity on wet pavement formula is established.It presents the tire-water-slope finite element modeling process.Through comparing the deformation rule of the loaded tire on horizontal ground and slope ground,analyses the tire grade ability on wet ground,and concludes the relationship between the tire load and the angle.Meanwhile compares the contact force change progress with the increased velocity when driving on the α=3°and α=8°pavement.And it estimates the critical velocity on wet slope.更多还原
