ANSYS实验分析报告

ANSYS实验分析报告（张刚机电研1005班）1ANSYS实验分析报告（张刚机电研1005班）实验一ANSYS软件环境1.问题描述如图所示，使用ANSYS分析平面带孔平板，分析在均布载荷作用下板内的应力分布。已知条件：F＝20N/mm，L＝200mm，b＝100mm，圆孔半径r＝20，圆心坐标为（100，50），E＝200Gpa。板的左端固定。图1-1带孔平板模型示意图实例类型：ANSYS结构分析分析类型：线性静力分析单元类型：PLANE822.实验内容图1-2有限元模型图2图1-3载荷与约束图图1-4模型变形图3图1-5等值线位移图由上图可知模型从左至右位移量逐渐递增，与实际情况符合。图1-6等值应力图从上可知，圆孔的上下端点应力最大，与实际情况符合，证明ANSYS分析正确。43.实验命令记录ANSYS命令流如下：/BATCH/COM,ANSYSRELEASE12.0.1UP2009041514:37:4803/15/2011/TITLE,plane/PREP7ET,1,PLANE82KEYOPT,1,3,3KEYOPT,1,5,0KEYOPT,1,6,0R,1,20,MPTEMP,,,,,,,,MPTEMP,1,0MPDATA,EX,1,,200000MPDATA,PRXY,1,,0.3BLC4,0,0,200,100CYL4,100,50,20ASBA,1,2FINISH/SOLFINISH/PREP7AESIZE,ALL,20,MSHKEY,0CM,_Y,AREAASEL,,,,3CM,_Y1,AREACHKMSH,'AREA'CMSEL,S,_YAMESH,_Y1CMDELE,_YCMDELE,_Y1CMDELE,_Y2SAVEFINISH/SOLFLST,2,1,4,ORDE,1FITEM,2,4/GODL,P51X,,ALL,FLST,2,1,4,ORDE,1FITEM,2,2/GOSFL,P51X,PRES,-1,/STATUS,SOLUSOLVEFINISH/POST1PLDISP,1PLDISP,0/EFACET,1PLNSOL,U,SUM,0,1.0/EFACET,1PLNSOL,S,EQV,0,1.0PLNSOL,U,XANCNTR,10,0.5/EFACET,1PLNSOL,S,EQV,0,1.0SAVEFINISH!/EXIT,ALL5实验二坝体的有限元建模及应力应变分析1.问题描述计算分析模型如图所示，分析坝体的应力、应变。实例类型：ANSYS结构分析分析类型：线性静力分析单元类型：PLANE42图2-12.实验内容图2-2有限元模型图图2-3载荷与约束图1m5m0.55m6图2-4模型变形图图2-5等值线位移图7图2-6等值应力图从上述结果可以看出，大坝斜边的顶点位移量最大，竖直边的顶点所受应力最大，为危险部分，这与实际情况是吻合的。3.实验命令记录ANSYS命令流如下：/BATCH/COM,ANSYSRELEASE12.0.1UP2009041514:07:3903/15/2011/TITLE,damSAVE/NOPR/PMETH,OFF,0KEYW,PR_SET,1KEYW,PR_STRUC,1KEYW,PR_THERM,0KEYW,PR_FLUID,0KEYW,PR_ELMAG,0KEYW,MAGNOD,0KEYW,MAGEDG,0KEYW,MAGHFE,0KEYW,MAGELC,0KEYW,PR_MULTI,0KEYW,PR_CFD,0/GO/COM,/COM,PreferencesforGUIfilteringhavebeensettodisplay:/COM,Structural/PREP7ET,1,PLANE42KEYOPT,1,1,0KEYOPT,1,2,0KEYOPT,1,3,2KEYOPT,1,5,0KEYOPT,1,6,0MPTEMP,,,,,,,,MPTEMP,1,0MPDATA,EX,1,,2.1e11MPDATA,PRXY,1,,0.3K,,0,0,0,K,,1,0,0,K,,1,5,0,K,,0.45,5,0,FLST,2,4,3FITEM,2,18FITEM,2,2FITEM,2,3FITEM,2,4A,P51XSAVEFLST,5,2,4,ORDE,2FITEM,5,1FITEM,5,3CM,_Y,LINELSEL,,,,P51XCM,_Y1,LINECMSEL,,_YLESIZE,_Y1,,,15,,,,,1FLST,5,2,4,ORDE,2FITEM,5,2FITEM,5,4CM,_Y,LINELSEL,,,,P51XCM,_Y1,LINECMSEL,,_YLESIZE,_Y1,,,20,,,,,1ACLEAR,1EPLOTMSHAPE,0,2DMSHKEY,1CM,_Y,AREAASEL,,,,1CM,_Y1,AREACHKMSH,'AREA'CMSEL,S,_YAMESH,_Y1CMDELE,_YCMDELE,_Y1CMDELE,_Y2FINISH/SOLFLST,2,2,4,ORDE,2FITEM,2,1FITEM,2,-2/GODL,P51X,,ALL,*DEL,_FNCNAME*DEL,_FNCMTID*DEL,_FNCCSYS*SET,_FNCNAME,'pre'*SET,_FNCCSYS,0!/INPUT,hanshu.func,,,1*DIM,%_FNCNAME%,TABLE,6,3,1,,,,%_FNCCSYS%!Beginofequation:1000*{X}*SET,%_FNCNAME%(0,0,1),0.0,-999*SET,%_FNCNAME%(2,0,1),0.0*SET,%_FNCNAME%(3,0,1),0.0*SET,%_FNCNAME%(4,0,1),0.0*SET,%_FNCNAME%(5,0,1),0.0*SET,%_FNCNAME%(6,0,1),0.0*SET,%_FNCNAME%(0,1,1),1.0,-1,0,1000,0,0,2*SET,%_FNCNAME%(0,2,1),0.0,-2,0,1,-1,3,2*SET,%_FNCNAME%(0,3,1),0,99,0,1,-2,0,0!Endofequation:1000*{X}!--FLST,2,1,4,ORDE,1FITEM,2,4/GOSFL,P51X,PRES,%PRE%/STATUS,SOLUSOLVEFINISH/POST1PLDISP,1/EFACET,1PLNSOL,U,SUM,0,1.0/EFACET,1PLNSOL,S,EQV,0,1.0SAVEFINISH!/EXIT,ALL
