如何实现轮子在轨道上滚动！
我做的东西 ，想模拟轮子在轨道上滚动，用Pilot 节点做，出现问题较多，<BR>一个是力不随节点移动，而且好像转动也实现不了，版主或那位高人有这样的例子，<BR>或有好的想法指点一下，在下郁闷很长时间了，谢谢<BR>QQ：154248326回复：（liqun）如何实现轮子在轨道上滚动！
一个原盘滚动的例子，不过没有用Pilot<BR><BR>例题是用GUI做的，因此命令流有些乱，不过是个调通的程序：<BR>/PREP7 <BR>!* <BR>ET,1,PLANE182 <BR>!* <BR>!* <BR>MPTEMP,,,,,,,, <BR>MPTEMP,1,0 <BR>MPDATA,EX,1,,6.9e4 <BR>MPDATA,PRXY,1,,0.32 <BR>TB,BISO,1,1,2, <BR>TBTEMP,0 <BR>TBDATA,,31,200,,,, <BR>SAVE <BR>RECTNG,0,10,0,2, <BR>FLST,2,2,8 <BR>FITEM,2,10,7,0 <BR>FITEM,2,10,12,0 <BR>CIRCLE,P51X, , , ,360,4, <BR>GPLOT <BR>SAVE <BR>FLST,5,1,4,ORDE,1 <BR>FITEM,5,3 <BR>CM,_Y,LINE <BR>LSEL, , , ,P51X <BR>CM,_Y1,LINE <BR>CMSEL,,_Y <BR>!* <BR>LESIZE,_Y1, , ,20, , , , ,1 <BR>!* <BR>FLST,5,1,4,ORDE,1 <BR>FITEM,5,2 <BR>CM,_Y,LINE <BR>LSEL, , , ,P51X <BR>CM,_Y1,LINE <BR>CMSEL,,_Y <BR>!* <BR>LESIZE,_Y1, , ,5, , , , ,1 <BR>!* <BR>MSHAPE,0,2D <BR>MSHKEY,1 <BR>!* <BR>CM,_Y,AREA <BR>ASEL, , , , 1 <BR>CM,_Y1,AREA <BR>CHKMSH,'AREA' <BR>CMSEL,S,_Y <BR>!* <BR>AMESH,_Y1 <BR>!* <BR>CMDELE,_Y <BR>CMDELE,_Y1 <BR>CMDELE,_Y2 <BR>!* <BR>GPLOT <BR>SAVE <BR>!* <BR>!* <BR>/COM, CONTACT PAIR CREATION - START <BR>CM,_NODECM,NODE <BR>CM,_ELEMCM,ELEM <BR>CM,_LINECM,LINE <BR>CM,_AREACM,AREA <BR>/GSAV,cwz,gsav,,temp <BR>MP,MU,1,0.2 <BR>MAT,1 <BR>MP,EMIS,1,7.88860905221e-031 <BR>R,1 <BR>REAL,1 <BR>ET,2,169 <BR>ET,3,172 <BR>R,1,,,1.0,0.1,, <BR>RMORE,,,1.0E20,0.0,1.0, <BR>RMORE,0.0,0,1.0,0,0,0.5 <BR>RMORE,,,1.0,0.0 <BR>KEYOPT,3,2,0 <BR>KEYOPT,3,3,0 <BR>KEYOPT,3,4,0 <BR>KEYOPT,3,5,0 <BR>KEYOPT,3,7,0 <BR>KEYOPT,3,8,0 <BR>KEYOPT,3,9,0 <BR>KEYOPT,3,10,0 <BR>KEYOPT,3,11,0 <BR>KEYOPT,3,12,0 <BR>KEYOPT,2,2,0 <BR>KEYOPT,2,3,0 <BR>!
