adams仿真出错

一个较复杂的装配体设定好条件仿真,可是一开始就停止了,说是找不到初始位置,有人知道是怎么解决的吗?

The Initial Conditions displacement solution failed.  ADAMS/Solver could
not determine the initial assembled position configuration of the model.
1)Try increasing the number of iterations for convergence.  Current value: 25.
2)If redundant constraints are present try to eliminate as many as possible.
3)Make sure prescribed motions are consistent with other aspects of the
  current model position.
4)Check to see if joints are inconsistent (contradictory); eliminate them if so.
5)Check to see if parts are not too distant from an assembled configuration.

楼主解决了吗？ 刚开始学adams 请多指点
