摘　　要：以205/55R18子午线轮胎为例,采用有限元仿真方法分析子午线轮胎的静态力学特性。建立有限元模型,并验证该模型的可靠性,在此基础上分析径向负荷、充气压力和接地摩擦因数对轮胎接地压力、纵向刚度和横向刚度的影响。结果表明:轮胎的径向负荷增大时,轮胎的接地压力、纵向刚度和横向刚度相应增大;轮胎的充气压力增大时,轮胎的接地面积减小,接地压力和刚度增大;通过增大摩擦因数可以提高轮胎的接地性能和操控性能,但摩擦因数的影响程度相比于径向负荷和充气压力较小。Taking the 205/55R18 radial tire as an example,the static mechanical properties of radial tires were analyzed using finite element simulation.A finite element model was established and its reliability was verified,based on those the effects of radial load,inflation pressure and ground friction coefficient on tire ground contact pressure,longitudinal stiffness and lateral stiffness were analyzed.The results showed that when the radial load of the tire increased,the ground contact pressure,longitudinal stiffness and lateral stiffness of the tire correspondingly increased.When the inflation pressure of the tire increased,the ground contact area of the tire decreased,and the ground contact pressure and stiffness of the tire increased.Increasing the coefficient of friction could improve the ground contact performance and handling performance of the tire,but the effect of the coefficient of friction was smaller than that of the radial load and inflation pressure.
