接触分析中正确设置过盈配合选项

killer2008

分析当中含有过盈配合，有2种方式设置，一是在几何上就包含过盈量，二是几何上没有过盈量，在ansys中设置。我比较喜欢用第二种，改起来很方便。
现在有个轴和轴套之间过盈0.03mm
主要设置Keyopt（5)=1  keyopt(9)=3  conf=0.03
下面是check的信息

Max.  Initial penetration 3.E-02 was detected between contact element   
4040 and target element 3974.                                          
You may move entire target surface by : x= -6.0241973E-08, y=           
1.704376994E-02, z= -2.468825442E-02,to reduce initial penetration.

1 CONTACT PAIR IS SELECTED
     CONTACT PAIR HAVING REAL ID =     1 IS INITIALLY CLOSED
