我用EXCITE PU做活塞缸套動力學計算是發(fā)散：

結(jié)果顯示：the relative displacement between two bodies is too large！

                 User action：（a）check the initial distances of the connected bodies.

                                        (b)  check the initial positions of the connected bodies.

                                        (c) if this error occures not occures at the beginning of the simulation,check in the animation of the problem the motion behaviour of the connected bodies。

動畫顯示活塞裙部部分節(jié)點跑出。不知道具體是哪里出現(xiàn)了問題，希望有經(jīng)驗的大神指導討論一下，謝謝
