WARNING:    After 50 iterations of the calculations for the initial conditions, the
   mechanism has been assembled with a maximum-magnitude error of -0.17745
   which does not satisfy the specified tolerance of 1.0E-10 .
WARNING:    The symbolic refactorization failed.  The matrix is structurally singular
   at time = 1.50E-02.
ERROR:      The simulation is terminating at time = 0.0.
  
   ADAMS can not solve the equations of motion because the mechanism has
   "locked up."    At least one constraint  can  no longer be satisfied.
   ADAMS is unable to satisfy the constraint for: JOINT MPRO_model.JOINT_33 .
ERROR:   Lockup detected




希望能得到大侠的指点啊,先谢谢了!

经过本人修改,出错提示如下:
WARNING:    The corrector has not converged after 1 attempts. No. of iterations = 6.
WARNING:    ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
   NOTE:  The set of redundant constraints has changed at time = 1.97528E-03.
