<P>!对于地震波的输入,可以把荷载记录做成文件,利用apdl的读取功能读入倒数据库中,下面的例子。 <BR>fini <BR>/config,nres,1000 <BR>*dim,aceX,TABLE,3000,1 <BR>*dim,aceY,TABLE,3000,1 <BR>*dim,aceZ,TABLE,3000,1 <BR>*creat,ff <BR>*vread,aceX(1,1),acex,txt,,1 <BR>(e16.6) <BR>*vread,aceX(1,0),ACETT,,,1 <BR>(e17.6) <BR>ACEX(0,1)=1 <BR>*end <BR>/input,ff <BR>*creat,ff <BR>*vread,aceY(1,1),acey,txt,,1 <BR>(e16.6) <BR>*vread,aceY(1,0),ACETT,,,1 <BR>(e17.6) <BR>ACEY(0,1)=1 <BR>*end <BR>/input,ff <BR>*creat,ff <BR>*vread,aceZ(1,1),acez,txt,,1 <BR>(e16.6) <BR>*vread,aceZ(1,0),ACETT,,,1 <BR>(e17.6) <BR>ACEZ(0,1)=1 <BR>*end <BR>/input,ff <BR>!地震波时程记录分成了3个文件,每个文件是一列。分别记录x,y,z方向的加速度。acett是时间记录。 <BR>这样就可以把加速度记录读取倒ansys数据库中作为数组。 <BR> <BR>下面是计算部分语句: <BR>/SOLU <BR>ANTYPE,trans <BR>!求解其自己选了 <BR>TM_START=0.01 <BR>TM_END=15.00 <BR>TM_INCR=0.01 <BR>*DO,TM,TM_START,TM_END,TM_INCR <BR>TIME,tm <BR>alpha, <BR>BETAD, <BR>ACEL,acex(tm),acey(tm),acez(tm) <BR>SOLVE <BR>*ENDDO <BR>fini</P> |
