摘要
轮胎接地压力分布非对称性对车辆燃油经济性、轮胎磨损以及轮胎动力学特性都有重要影响。建立了205/55R16型半钢子午线轮胎的有限元模型,并设计静压实验进行了验证,考察了稳态滚动工况下各类参数对于接地压力分布非对称指数的影响规律。结果表明:+50%和–50%的变化范围内,各类参数对接地压力分布的非对称性的影响均呈现非线性,影响程度排序依次为带束层角度、充气压力、滚动速度和垂向载荷。垂向载荷和滚动速度的增加会提高非对称指数,充气压力和带束层帘线角度会降低非对称指数。
The asymmetric pressure distribution in tire contact patch has significant impact on the vehicle fuel economy, tire wear and tire dynamics. In this paper, a FEA model for 205/55R16 semi-steel radial tire was built and verified by static pressure experiments. The influences of tire structural parameters and vehicle driving parameters on asymmetry factor for exploring the asymmetry of the pressure distribution in contact patch were investigated in the steady-state rolling condition. The results show that the influence of the parameters ranging from ＋50% to -50% on the asymmetry factor of the contact pressure distribution is nonlinear. The impact order in sequence is tire belt cord angle, tire inflation pressure, velocity and vertical load. The increase of the vertical load and velocity lead to the greater asymmetry factor whereas the inflation pressure and the belt cord angle have the negative effects.
