ADAMS 仿真错误 每个零件都定义质量了 不知道哪错了 求大神

警告:
The Reconcile Acceleration-Force has detected a singular Jacobian matrix.
This problem may be caused by:
(a) A constraint equations that became almost redundant, e.g., the model
is at a singular configuration or at a bifurcation point.
(b) A massless PARTS in the model.

The Sparse Solver has detected a zero pivot for row 1318 (during the symbolic pivot selection).
The corresponding equation is: Part/221 Psi Torque

A minimization algorithm will be used to find a solution on the
projected constraint manifold.
错误: Time 4.414045E-01:
Acceleration computation failed to converge after 25 iterations.
Equation with the largest imbalance: Part/221 Theta Torque
Imbalance = -2.352992253E+06
Variable receiving largest increment: Part/2 X Acc
Delta = 0.000000000E+00
1) Check mass and inertia properties to ensure they are valid.
2) Make sure the choice of units is appropriate for the system.
Systems that have very small inertias may benefit from "small"
force units, e.g., dynes.
3) Check that motion generators are valid and no redundant constraints exist.
4) Check if impact functions caused a strange response in the model (verify properties).
5) An IMPLICIT DIFF element which does not reference DIF1 must be satisfied by its IC.

Answer 1

你可能是joint弄得不好，约束中有过约束或者是设置得有问题。
可以把约束删除，再仔细弄一遍。在再次添加约束的时候，变换一下添加的点的位置。

Answer 2

请问问题解决了吗？我也遇到相同的问题了。。
