WARNING: An anomalous situation has been detected for TIRE Vehicle.TIRE_4.
==============================================
上面的WARNING是说四个轮子用的一样
可能咋样咋样
这个可以不管它
==============================================
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 = 5.5617
这个是说产生滚动阻力矩的法向力臂大于轮胎与地面接触面一半的长度
CRR coefficence of rolling resistence滚动阻力系数
==============================================
WARNING: ADAMS has issued 4 warning(s) for the normal force moment arm
for the rolling resistance moment. ADAMS will no longer
issue these warnings.
估计是ADAMS累了
==============================================
WARNING: For TIRE Vehicle.TIRE_2 the absolute value of the longitudinal slip ratio
has gone beyond its maximum allowable limit of 1.0.
Longitudinal slip ratio = 1.0016.
纵向的滑移率大于可许值1
（怪不得我的车在原地空转）
==============================================
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).
这个也是对的
==============================================
WARNING: For TIRE Vehicle.TIRE_4 the absolute value of the longitudinal slip ratio
has gone beyond its maximum allowable limit of 1.0.
Longitudinal slip ratio = 1.0012.
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: For TIRE Vehicle.TIRE_4 the absolute value of the longitudinal slip ratio
has gone beyond its maximum allowable limit of 1.0.
Longitudinal slip ratio = 1.0068.

negative, it will be set to -1.0 (traction).
WARNING: A total of 20 warnings have been issued for trimming of slip
values that have exceeded their limits. ADAMS will no longer
issue warnings when it trims longitudinal slip ratios,
lateral slip ratios due to slip angle, lateral slip ratios
due to combined slip and camber angles, and comprehensive
slip values.

===================================
The greatest error in an equation is 1.06789E-04 in the
equation for GFORCE Vehicle.TIRE_2.GFORCE_17043457 .
The greatest change in a variable is 2.35073E-15 in the
variable for PART Vehicle.center_link .
Try the following in this order:
1. Use the MAXIT argument on the EQUILIBRIUM, IC, KINEMATICS,
or INTEGRATOR command to increase the maximum number of
iterations.
2. Temporarily change the value of the PATTERN argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command to
  ATTERN = T.
3. Temporarily increase the value of the ERROR argument on the
EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at
time = 2.5719 .
4. If one or more forces change rapidly or sharply near
time = 2.5719, modify the force or forces.
ERROR: Simulation failure detected

怎么办吧？
