ADMAS求解时锁住

chw007700

请大家给我翻译下面这短话。迫切需要，非常感谢！ At time  4.551652511E-01 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
