你是不是想给放平啊,那你就重新画下,图形旋转45°

为什么仿真会出错啊?
错误提示如下:
---- ERROR ----
   The system matrix has a zero pivot for column 1013, which is associated
   with VARIABLE/4 Algb Var.Consequently, the matrix is numerically singular.
   The system has 105 kinematic degrees of freedom.

   ID = 1
请问是什么意思啊?

-------------------------------------------
找出与 column 1013相连的零件,查看此零件的信息,是这个零件导致计算不能收敛!

谢谢!

panyx0101 发表于 2008-3-12 20:14:12

你有没有试国过2007r2里面的SmartDriver做双扭线试验,我现在正作着,还有点问题:Q

sophieyuan1984 发表于 2008-3-12 21:28:23

我的问题已经解决了,主要是仿真的车速过高的原因。谢谢各位了!

双扭线试验是定速试验,好像用不着SmartDriver

楼主问题解决了吗?我按二楼的回答把数据旋转45度,轨迹还是不正的8,这是怎么回事啊:'(

kyle_sy 发表于 2014-11-10 18:21:59

我也是这个问题,不是正的8,同问解决办法
