谁在ansys下建过螺丝钉模型?
认识的人都是从其他软件导入,我在ansys下建了一个,但划分网格存在问题,并且网格密度太大,否则要出错,不知各位有何高见。可发信至<a href="mailtscwk83@163.com" target="_blank" >scwk83@163.com</A>联系<BR>APDL命令如下:<BR>/prep7<BR>et,1,solid186<BR>mp,ex,1,2e11<BR>mp,prxy,1,0.3<BR>k,,1.5<BR>k,,,0.5,-1.5<BR>k,,-1.5,1 <BR>k,,,1.5,1.5<BR>k,,1.5,2 <BR>k,,1.3,0.25<BR>k,,1.3,-0.25<BR>k,,2,0.85<BR>k,,2,-0.85 <BR>numcmp,all <BR>csys,5<BR>*do,i,1,4<BR>l,i,i+1<BR>*enddo<BR>csys,0<BR>a,6,7,9,8<BR>*do,i,1,4<BR>vdrag,1+5*(i-1),,,,,,i<BR>*enddo<BR>ldele,1,4,1,1<BR>vadd,all<BR>numcmp,all<BR>vgen,10,1,,,,2<BR>btol,1.8e-004, <BR>vglue,all<BR>wpstyl,,,,,,,,1<BR>wpoff,,-1<BR>wprot,,-90<BR>cyl4,,,2,,,,25<BR>numcmp,all<BR>vsbv,1,all<BR>vplot<BR>wprot,,90<BR>wpoff,,25<BR>wprot,,90<BR>cyl4,,,4,,,,-2<BR>wpoff,,,25<BR>con4,,,2,0.1,4<BR>wpcsys,-1,0<BR>wpstyl,,,,,,,,0<BR>vadd,all<BR>block,-5,5,25,28,-0.4,0.4<BR>vsbv,3,1<BR>numcmp,all回复:(wannatop)谁在ansys下建过螺丝钉模型?

<P>多谢。不过那个模型螺纹和柱体之间不能进行布尔操作,连不成一个有联系的体,这样分析时肯定不对的,而且那个模型单对螺纹网格划分时结果十分不理想,划到几万个单元才看起来比较可以。我建的那个虽然网格划分要出警告,但毕竟是一个有机体啊。有没有其他办法啊?</P>
