船底板架.doc

一油船船底的板架组合结构图，结构的四周为刚性固定，纵向构件的截面为倒T形，尺寸为，它距周界的距离为3m，横向构件的截面为L形，尺寸为，横向构件的间距为3m，在横向构件上受到均布载荷的作用，其大小为1000㎏/㎡，分析此结构的变形和应力。 采用自顶向下的建模方法： 分别输入板长边和短边方向的坐标生成矩形平面： 2．利用插入法生成长边和短边方向的等分点： 3．在几个关键点之间创建直线（注意：直线必须建立在平面上）： 4.设置单元的类型和材料属性： 5.建立Z方向上的点： 6定义梁截面： 7对线和面定义单元属性： 8划分单元格： 9在面上施加均布载荷： 10定义边界条件（四周刚性固定）： 11载荷求解： 12把结果读入到数据库： 13显示变形前后的结构：  14绘制等值线： Log文件： /BATCH /COM,ANSYS RELEASE 12.1 U 10:38:21 05/30/2010 /input,menust,tmp,,,,,,,,,,,,,,,,,1 /GRA,POWER /GST,ON /PLO,INFO,3 /GRO,CURL,ON /CPLANE,1 /REPLOT,RESIZE WPSTYLE,,,,,,,,0 /PREP7 RECTNG,0,12,0,6, !* KFILL,1,2,3,100,1,1, !* KFILL,4,3,3,200,1,1, !* KBETW,4,1,0,RATI,0.5, !* KBETW,3,2,0,RATI,0.5, LAREA, 200, 100, 1 LAREA, 201, 101, 1 LAREA, 202, 102, 1 LAREA, 5, 6, 1 !* SAVE SAVE SAVE SAVE !* ET,1,BEAM188 !* ET,2,SHELL63 !* R,1,0.01, , , , , , RMORE, , , , RMORE RMORE, , !* !* MPTEMP,,,,,,,, MPTEMP,1,0 MPDATA,EX,1,,2e10 MPDATA,PRXY,1,,0.3 K,1000,3,0,1, K,2000,6,0,1, K,3000,9,0,1, K,4000,0,3,1, SAVE SAVE SECTYPE, 1, BEAM, T, one, 0 SECOFFSET, USER, 0, 0.2 SECDATA,0.4,0.2,0.01,0.01,0,0,0,0,0,0 SECTYPE, 2, BEAM, L, two, 0 SECOFFSET, USER, 0, 0.1 SECDATA,0.2,0.1,0.01,0.01,0,0,0,0,0,0 FLST,5,3,4,ORDE,2 FITEM,5,5 FITEM,5,-7 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,S,_Y !* !* CMSEL,S,_Y1 LATT,1,1,1, , , ,2 CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* FLST,5,3,4,ORDE,2 FITEM,5,5 FITEM,5,-7 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,,_Y !* LESIZE,_Y1, , ,30, , , , ,1 !* CM,_Y,LINE LSEL, , , , 8 CM,_Y1,LINE CMSEL,S,_Y !* !* CMSEL,S,_Y1 LATT,1,1,1, , , ,1 CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* FLST,5,1,4,ORDE,1 FITEM,5,8 CM,_Y,LINE LSEL, , , ,P51X CM,_Y1,LINE CMSEL,,_Y !* LESIZE,_Y1, , ,60, , , , ,1 !* CM,_Y,AREA ASEL, , , , 1 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT,
