[問題] SolidWorks COSMOSMotion(Simulation)
在COSMOSMotion分析裡
有時候會出現這樣的錯誤訊息:
At time X.XXXE-0X 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 mass on a part with an unconstrained
translation degree of freedom.
Make sure you have mass on all parts with translation degrees of freedom.
(4) The system includes a zero 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.
我的翻譯是這樣:
在時間點X.XXXE-0X時,積分不能進行。 可能的原因︰
(1) 無法取得要求的準確數值解。解決方法:增加可接受的誤差。
(2) 多餘的限制條件,鎖住,或者分歧。後兩者表示是機製設計問題。
(3) 可能有自由度不受限制、零質量的零件。解決方法:確認零件是否有質量。
(4) 可能有自由度不受限制、零轉動慣量的零件。解決方法:確認零件是否有轉動慣量。
(5) 第五個我看不懂,可能跟分析軟體的程式語言有關。
請問有人對這些有研究嗎?
或者 當出現這些訊息時 我該怎麼去了解是哪一個錯誤的發生呢?
怎麼解決 或者如何驗證
希望有人可以給點這方面的資訊 麻煩了 謝謝
