ADAMS仿真时出错，请众位英雄，大侠帮忙找下原因

浪角

ADAMS仿真的时候出现如下错误提示，请众位英雄帮忙看下是什么原因。万分感谢，好人一生平安！！
ERROR:   At time  5.699663786E-02 the integrator is unable to proceed.  Possible Causes:
(1) The accuracy required for the numerical solution can not be attained.
Relax (increase) the value of the acceptable integration ERROR.
(2) Incompatible redundant constraints, a lock up, or a bifurcation
situation.  The latter two indicate a mechanism design problem.
(3) The system includes a zero (or relatively small) mass on a part with
an unconstrained translational degree of freedom.
Make sure you have mass on all parts with translational degrees of freedom.
(4) The system includes a zero (or relatively small) inertia on a part
with an unconstrained rotational degree of freedom.
Make sure you have inertias on all parts with rotational degrees of freedom.
(5) An Adams element has a function expression that equals exactly itself.
For example,
     SFORCE/id1,I=id2,J=id3,ROT,FUNC=SFORCE(id1,jflag,comp,rm),and
     DIFF/id4,IMPLICIT,IC=0,FUNC=DIF1(id4).
Similarly,
     VARIABLE/id5, FUNC=VARVAL(id5)*TIME
equals itself at 1 second. Avoid setting an Adams element equal to itself.

这个问题每隔几天就有人问，自己搜一下吧？？？

个人认为，这类问题多属冗余约束所致，可以利用model verify检查一下模型。论坛有专门讲述冗余约束的帖子，可以按照帖子教程，针对model verify的结果进行修改~~~

http://forum.simwe.com/thread-1002343-1-1.html还有一点，仿真步长也是一个敏感问题~~~步长不合理也会导致出错

明显提示你质量信息不完整了~~~~

有三点可能原因：模型存在冗余约束、约束不合理、求解器设置不够合理
