求解：在adams/view中建的轮胎模型的警告提示

各位大侠，我在adams/view中建立了一个轮胎道路模型（UA）在运行时总是出现这种警告，请指教这是怎么回事，给个解决的提示。    我是菜鸟
谢谢！
WARNING:    For TIRE zhengche.TIRE_4 the absolute value of the longitudinal slip ratio
   has gone beyond its maximum allowable limit of 1.0.
  
   Longitudinal slip ratio = 2.1027.
  
   If the longitudinal slip ratio is positive, it will be set
   to 1.0 (braking).  If the longitudinal slip ratio is
   negative, it will be set to -1.0 (traction).
WARNING:    An anomalous situation has been detected for TIRE zhengche.TIRE_1.
   The moment arm for normal force (Fz) that causes the
   rolling resistance moment (Ty) is greater than the allowable
   maximum of 1/2 the length of the contact patch.
  
   CRR = 6.250
   CRR_max = 1.23886E-05
WARNING:    Note regarding TIRE zhengche.TIRE_2.
   Its Road Data File (E:/work/adams documents/zhengchemoxing/275r22.5_flat.rdf) is the same as the one for TIRE zhengche.TIRE_1,
   and you have the RGRA argument on both TIRE statements.
   ADAMS/Solver will generate redundant road graphics which
   may slow graphics and animation in particular.
   Include the RGRA argument on only one of these TIRE statements.

把仿真精度调低试试!
