标题: 按照实例教程做的jeep，大家提提意见
按照实例教程做的jeep，但是加上力矩之后基本上没看到什么明显的运动，还有，仿真时有一堆警告，请大家给提提意见，我再修改修改。
谢谢了。

1.你的力矩加错了
一个加到轮胎上
你加到地面上了

2.首先得提示是

WARNING: Model .jeep is no longer compatible with the ADAMS/Solver (C++).
.jeep.TIRE_1 is causing the incompatibility because:

   1) Objects of type Tire are not compatible with the
      ADAMS/Solver (C++).

   2) The topology of the model has changed so .jeep.TIRE_1
      is no longer connected in a way that is compatible with the
      ADAMS/Solver (C++).

   3) An attribute of .jeep.TIRE_1 is no longer compatible with
      the ADAMS/Solver (C++).

If you intend to use the ADAMS/Solver (C++), then be sure that you
set your preferences so ADAMS/Solver (C++) is the default as follows:

   - From the Settings menu, point to Solver and select either
     Solver Executable or Preferences, depending on the product
     you are using.

   - Press F1 in the dialog box that appears to learn more.

If you do not want to use the ADAMS/Solver (C++), you must change
your model to eliminate the incompatibilty.  See the online help
for the object listed for more information.

2003可能有了重大变化
以前是可以的

  3.  The greatest error in an equation is 1.87514E+08 in the
   equation for GFORCE jeep.TIRE_1.GFORCE_16912385 .
  
   The greatest change in a variable is 1.5601 in the
   variable for PART jeep.TIRE_3.PART_17171457 .
  
   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
          &nbsp

ATTERN = T.
       3.  Temporarily increase the value of the ERROR argument on the
           EQUILIBRIUM, IC, KINEMATICS, or INTEGRATOR command at
           time = 2.1663 .
       4.  If one or more forces change rapidly or sharply near
           time = 2.1663, modify the force or forces.
  
ERROR: Simulation failure detected

谢谢 corneringF !

我也正在做这个例子。Steering_wheel、Steering_shaft、Steering_gear之间分别有两个万向节副，总是有一个万向节副有错误：
   WARNING: JOINT JEEP.JOINT_23 is not specified correctly.
   The angle between the positive z-axis of the I marker and
   the positive z-axis of the J marker is 13.181 degrees.
   The angle between the positive z axes should be greater than
   30 degrees.
这是怎么回事？
请xiumin和corneringF 帮帮忙！先谢了！
