仿真问题

请教各位高手：我在adams/view中建立的汽车悬架模型，出现以下警告，不知什么原因。望帮帮小弟。谢谢！
WARNING:    An anomalous situation has been detected for TIRE b_jeep.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 = 5.6250
   CRR_max = 2.36568E-02
WARNING:    For TIRE b_jeep.TIRE_3 the absolute value of the longitudinal slip ratio
   has gone beyond its maximum allowable limit of 1.0.
  
   Longitudinal slip ratio = 4.97331E+06.
  
   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).

很清楚是你的 Longitudinal slip ratio = 4.97331E+06取值太大了， Longitudinal slip ratio 得范围在+1~-1，不填为-1

感谢你的解答。想问一下，在哪里修改 Longitudinal slip ratio  
tire文件中吗还是………………
再次感谢！

查看李军出的书中的有关整车模型的例子，里面有关于轮胎文件参数的解释，或者察看帮助文档，个人认为应该在轮胎文件里修改。

感谢hero75816的热切解答，在下不胜感激！不过 Longitudinal slip ratio 的设置好象只有一个固定值，如何设置 Longitudinal slip ratio 啊？我试着改了几个值，问题还在。还望高手帮小弟看看！
