大家好!我在弄平板對(duì)接多道焊的熱結(jié)構(gòu)耦合分析，但是遇到一些問(wèn)題，第一道焊縫和第二道焊縫冷卻后最低溫度低于室溫，有的還變成了負(fù)的，第三道焊縫冷卻后溫度是正常的，請(qǐng)問(wèn)這是什么原因呢？下面是我的命令流，可以指導(dǎo)一下嗎？ /FILNAME,fuxian,0 /PREP7 /UNITS,SI !定義焊接參數(shù) ET,1,SOLID70 !!熱分析單元 TOFFST,273 MPTEMP,,,,,,,, !定義溫度 MPTEMP,1,20 MPTEMP,2,100 MPTEMP,3,210 MPTEMP,4,330 MPTEMP,5,420 MPTEMP,6,540 MPTEMP,7,660 MPTEMP,8,780 MPTEMP,9,985 MPTEMP,10,1320 MPTEMP,11,1420 MPTEMP,12,1500 MPDATA,KXX,1,,51 !定義導(dǎo)熱系數(shù) MPDATA,KXX,1,,50 MPDATA,KXX,1,,49 MPDATA,KXX,1,,46 MPDATA,KXX,1,,41 MPDATA,KXX,1,,38 MPDATA,KXX,1,,34 MPDATA,KXX,1,,28 MPDATA,KXX,1,,25 MPDATA,KXX,1,,32 MPDATA,KXX,1,,42 MPDATA,KXX,1,,42 MPDATA,C,1,,450 !定義比熱容 MPDATA,C,1,,475 MPDATA,C,1,,530 MPDATA,C,1,,560 MPDATA,C,1,,630 MPDATA,C,1,,720 MPDATA,C,1,,830 MPDATA,C,1,,910 MPDATA,C,1,,1055 MPDATA,C,1,,2000 MPDATA,C,1,,2100 MPDATA,C,1,,2150 MPDATA,DENS,1,,7860 !定義密度 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,DENS,1,,7860 MPDATA,EX,1,,210.0E9 !定義彈性模量 MPDATA,EX,1,,195.0E9 MPDATA,EX,1,,195.0E9 MPDATA,EX,1,,185.0E9 MPDATA,EX,1,,168.0E9 MPDATA,EX,1,,118.0E9 MPDATA,EX,1,,52.0E9 MPDATA,EX,1,,12.0E9 MPDATA,EX,1,,11.8E9 MPDATA,EX,1,,10.4E9 MPDATA,EX,1,,10.2E9 MPDATA,EX,1,,10E9 MPDATA,PRXY,1,,0.260 !定義泊松比 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 MPDATA,PRXY,1,,0.260 UIMP,1,REFT,,,20 MPDATA,ALPX,1,,11.2E-6 !定義膨脹系數(shù) MPDATA,ALPX,1,,11.8E-6 MPDATA,ALPX,1,,12.4E-6 MPDATA,ALPX,1,,13.1E-6 MPDATA,ALPX,1,,13.6E-6 MPDATA,ALPX,1,,14.1E-6 MPDATA,ALPX,1,,14.6E-6 MPDATA,ALPX,1,,14.6E-6 MPDATA,ALPX,1,,14.6E-6 MPDATA,ALPX,1,,14.6E-6 MPDATA,ALPX,1,,14.6E-6 MPDATA,ALPX,1,,14.6E-6 TB,BISO,1,6 TBTEMP,20 TBDATA,,380E+6,210.0E8 TBTEMP,210 TBDATA,,320E+6,195.0E8 TBTEMP,420 TBDATA,,190E+6,168.0E8 TBTEMP,660 TBDATA,,75E+6,52.0E8 TBTEMP,1320 TBDATA,,28E+6,10.4E8 TBTEMP,1500 TBDATA,,20E+6,10E8 !!建立幾何模型 L=300E-3 !焊件的長(zhǎng)度 W=250E-3 !焊件的寬度 H=6E-3 !焊件的高度 H1=4E-3 !第一道焊縫高度 H2=2E-3 !第二道和第三道焊縫高度 Ww=24E-3 !焊縫寬度 BLOCK,0,Ww/2,0,-H,0,W, BLOCK,0,-Ww/2,0,-H,0,W, BLOCK,Ww/2,Ww/2+30e-3,0,-H,0,W, BLOCK,Ww/2+30e-3,Ww/2+40e-3, 0,-H,0,W, BLOCK,Ww/2+40e-3,L/2,0,-H,0,W, BLOCK,-Ww/2,-Ww/2-30e-3,0,-H,0,W, BLOCK,-Ww/2-30e-3,-Ww/2-40e-3, 0,-H,0,W, BLOCK,-Ww/2-40e-3,-L/2,0,-H,0,W, wpro,,90.000000, wpof,,,H2 RECTNG,-0.3,0.3,-0.3,0.3, FLST,2,8,6,ORDE,2 FITEM,2,1 FITEM,2,-8 VSBA,P51X, 49 VGLUE,ALL WPCSYS,,0 !!劃分網(wǎng)格 LESIZE,12,,,W/2e-3 LESIZE,112,,,H2/2e-3 LESIZE,104,,,H1/2e-3 FLST,2,2,4,ORDE,2 FITEM,2,8 FITEM,2,103 LESIZE,P51X,,,Ww/2/2e-3 VMESH,4 VMESH,10 VMESH,1 VMESH,9 ESIZE,2E-3 FLST,2,4,6,ORDE,4 FITEM,2,2 FITEM,2,3 FITEM,2,5 FITEM,2,6 VMESH,P51X ESIZE,3E-3 FLST,2,4,6,ORDE,4 FITEM,2,7 FITEM,2,8 FITEM,2,27 FITEM,2,28 VMESH,P51X ESIZE,5E-3 FLST,2,4,6,ORDE,4 FITEM,2,25 FITEM,2,26 FITEM,2,29 FITEM,2,30 VSWEEP,P51X !!溫度場(chǎng) !第一道焊縫參數(shù) v1=0.22/60 !焊接速度 I1=190 !電流 U1=22 !電壓 !第二道焊縫參數(shù) v2=0.55/60 !焊接速度 I2=220 !電流 U2=27 !電壓 !第三道焊縫參數(shù) v3=0.52/60 !焊接速度 I3=220 !電流 U3=27 !電壓 !雙橢球熱源參數(shù) ff=0.6 fr=1.4 a1=4e-3 a2=3e-3 a3=3e-3 b1=4e-3 b2=3e-3 b3=3e-3 cf=4e-3 cr=8e-3 Q1=0.75*U1*I1/(100*v1) Q2=0.75*U2*I2/(100*v2) Q3=0.75*U3*I3/(100*v3) local,11,0,0,-H2,0,,,,1,1 local,12,0,-Ww/4,0,0,,,,1,1 local,13,0,Ww/4,0,0,,,,1,1 /SOL ANTYPE,4 TRNOPT,FULL !瞬態(tài)分析選項(xiàng)，完全分析 TUNIF,20, !初始溫度 NROPT,FULL,,ON !定義完全牛頓-拉普森方法，激活自適應(yīng)下降（默認(rèn)） KBC,1 AUTOTS,ON !自動(dòng)步長(zhǎng) LNSRCH,ON !線性搜索 OUTRES,ALL ,ALL PRED,ON !打開(kāi)預(yù)測(cè)校正 TIMINT,ON !時(shí)間積分設(shè)置 TINTP,,,,1,, !定義瞬態(tài)綜合參數(shù) TREF,20 !參考溫度 !把焊縫區(qū)的單元?dú)⑺?br /> FLST,5,4,6,ORDE,4 FITEM,5,1 FITEM,5,4 FITEM,5,9 FITEM,5,-10 VSEL,S, , ,P51X NSLV,R,1 ESLN,R,1, EKILL,ALL ALLSEL,ALL !第一道焊縫 *DEL,_FNCNAME *DEL,_FNCMTID *DEL,_FNC_C1 *DEL,_FNC_C2 *DEL,_FNC_C3 *DEL,_FNC_C4 *DEL,_FNC_C5 *DEL,_FNCCSYS *SET,_FNCNAME,'func1' *DIM,_FNC_C1,,1 *DIM,_FNC_C2,,1 *DIM,_FNC_C3,,1 *DIM,_FNC_C4,,1 *DIM,_FNC_C5,,1 *SET,_FNC_C1(1),ff *SET,_FNC_C2(1),Q1 *SET,_FNC_C3(1),a1 *SET,_FNC_C4(1),b1 *SET,_FNC_C5(1),cf *SET,_FNCCSYS,11 ! /INPUT,func1.func,,,1 *DIM,%_FNCNAME%,TABLE,7,42,1,,,,%_FNCCSYS% ! !

程序太長(zhǎng)，智能簡(jiǎn)單看了一下。提幾個(gè)建議，可以修改一下： 1 命令 KBC, 1 改為 KBC,0 將階梯式加載改為 斜坡方式加載，更符合實(shí)際情況。 2 所有的函數(shù)定義，移到使用該函數(shù)的命令之前。因?yàn)榘凑?ANSYS 的規(guī)定，函數(shù)中的所有參數(shù) (包括局部坐標(biāo)系) 都是使用該函數(shù)定義之前的數(shù)據(jù)，你的函數(shù)定義是在求解部分的最前面，其中的參數(shù)將固定為該處的值，不會(huì)隨著熱源的移動(dòng)而變化，與實(shí)際情況不符合。因而所有三道焊縫的計(jì)算結(jié)果都是錯(cuò)誤的。 3 多處 nsubst 命令，最好修改一下。該命令的格式是： NSUBST, 常規(guī)子步數(shù), 最大子步數(shù), 最小子步數(shù) 你的命令流中： 第一個(gè)： NSUBST,1 建議改為： NSUBST,5,5,1 其它的： NSUBST,400,200,500 ，不符合該命令的用法，建議改為： NSUBST, 10,1000,10 4 你的熱輻射的定義可能有問(wèn)題，由于我手頭沒(méi)有資料，暫時(shí)說(shuō)不出哪里有問(wèn)題，你可以先不施加熱輻射載荷，試試看是否冷卻后還出現(xiàn)你說(shuō)的問(wèn)題。 以上僅供參考，你不妨試試。 |
