ansys 焊接應(yīng)力場(chǎng)問題 已有2人參與
|

下面是我做的焊接應(yīng)力場(chǎng)，溫度場(chǎng)是對(duì)的，但是算應(yīng)力場(chǎng)時(shí)老出現(xiàn)下面的問題，求大神解決！�。� 附上命令流。 finish /filname /filname,al_fe_weld /title,al_fe_weld /units,si btol,1e-7 /prep7 len=0.1 wid=0.05 thic=0.0015 lnum=20 i=100 u=10 v=0.5/60 pi=acos(-1) eta=0.8 k=1.2e5 them0=25 qmax=k*eta*u*i/pi radius=0.06 et,1,solid70 mp,dens,1,8030 mp,dens,2,4850 mp,alpx,1,1.78e-5 mp,alpx,2,9.36e-6 mp,kxx,1,16.3 mp,kxx,2,7.44 mp,c,1,502 mp,c,2,544 k,1,0,0,0 k,2,0,0,0.1 l,1,2 rectng,0,0.0005,0,0.001 rectng,0,0.05,0,0.001 rectng,0,-0.05,-0.0005,0 rectng,0,-0.05,0,0.001 rectng,0,-0.05,0,0.0015 pcirc,0,0.0005,270,360 wpoffs,0,0.001,0 pcirc,0,0.0005,0,90 wpcsys vdrag,all,,,,,,1 vptn,all vglue,all nummrg,all numcmp,volume vplot /view,,2,4,3 /replot allsel lsel,s,,,88,91 lesize,all,,,50,10 allsel lsel,a lsel,s,,,10 lsel,a,,,44 lesize,all,,,50,0.1 allsel lsel,s,,,92 lsel,a,,,95 lsel,a,,,20 lsel,a,,,65 lsel,a,,,93 lsel,a,,,96 lesize,all,,,50,10 allsel lsel,s,length,,0.1 lesize,all,,,100 allsel esize,0.0005 vsel,s,,,1 vsel,a,,,4 mat,1 vsel,all vsel,s,,,2,3 vsel,a,,,5,7 mat,2 vsel,all vsweep,all,,,0 allsel finish /solu esel,all *get,nemax,elem,,num,max *get,nemin,elem,,num,min alls antype,trans trnopt,full nropt,full,,on pred,on timint,0,struct timint,1,thern tintp,0.005,,,1,0.5,0.2 tref,25 t=0 dt0=1e-6 dt1=0.5 tinc=len/(lnum*v) time,dt0 timint,off kbc,1 nsubst,1 esel,all nsle,s ic,all,temp,25 alls outres,all,all solve esel,all eplot *do,im,0,lnum,0.1 vsel,s,,,4 vsel,a,,,3 vsel,a,,,7 eslv,r nsle asel,s,area,,30 asel,a,area,,47 asel,a,area,,52 nsla,s,1 esln,r,0 c=v*tinc*im b=thic a=-0.0005 tm=dt1+im*tinc time,tm antype,4,vtrest timint,on autots,on kbc,1 deltim,0.1,0.1,0.2 *do,i,nemin,nemax,1 *if,esel(i),eq,1,then xsy=centrx(i) ysy=centry(i) zsy=centrz(i) rr=abs(sqrt((xsy-a)*(xsy-a)+(ysy-b)*(ysy-b)+(zsy-c)*(zsy-c))) *if,rr,le,radius,then qr=qmax*exp(-k*rr*rr) sfe,i,nmface(i),hflux,,qr *endif *endif *enddo asel,s,mat,,1 asel,a,mat,,2 asel,u,,,30 asel,u,,,47 asel,u,,,52 nsla,r sf,all,conv,200,293 allsel outres,all,all solve esel,all vsel,s,,,4 vsel,a,,,3 vsel,a,,,7 eslv,r nsle asel,s,area,,30 asel,a,area,,47 asel,a,area,,52 nsla,r,1 esln,r,0 *do,i,1,6 sfedele,all,i,hflux *enddo allsel *enddo esel,all eplot save finish /filname /filname,heat_stress /prep7 allsel esel,s,,type,2 etchg,tts mptemp,1,25,500,1000,1500,2000 mpdata,ex,1,1,1.93e11,1.5e11,0.7e11,0.1e11,0.01e11 mpdata,ex,2,1,1.02e11,0.5e11,0.08e11,0.001e11,0.0001e11 tb,bkin,1,5 tbtemp,25,1 tbdata,1,1200e6,0.193e11 tbtemp,500,2 tbdata,1,933e6,0.15e11 tbtemp,1000,3 tbdata,1,435e6,0.07e11 tbtemp,1500,4 tbdata,1,70e6,0.01e11 tbtemp,2000,5 tbdata,1,7e6,0.001e11 tb,bkin,2,5 tbtemp,25,1 tbdata,1,800e6,0.102e11 tbtemp,500,2 tbdata,1,400e6,0.05e11 tbtemp,1000,3 tbdata,1,70e6,0.008e11 tbtemp,1500,4 tbdata,1,1e6,0.0001e11 tbtemp,2000,5 tbdata,1,0.1e6,0.00001e11 mp,nuxy,1,0.29 mp,nuxy,2,0.3 finish /solu antype,trans solcontrol,off neqit,100 lumpm,0 allsel tref,25 autots,on kbc,1 lnsrch,1 trnopt,full nropt,full,,off allsel *do,im,0,12,1 tm=dt1+im time,tm ldread,temp,,,tm,0,al_fe_weld,rth solve *enddo finish wenti.JPG |

多謝，這個(gè)問題解決了。但是又出問題了 Temperatures for material properties must be in ascending order. The MPTEMP command is ignored. 我把命令流改為這樣了 mptemp,,,,,,,, mptemp,1,25 mptemp,2,250 mptemp,3,500 mptemp,4,750 mptemp,5,1000 mptemp,6,1500 mptemp,7,1700 mptemp,8,2500 mpdata,kxx,1,,50 mpdata,kxx,1,,47 mpdata,kxx,1,,40 mpdata,kxx,1,,27 mpdata,kxx,1,,30 mpdata,kxx,1,,35 mpdata,kxx,1,,14 mpdata,kxx,1,,14.2 mpdata,c,1,,460 mpdata,c,1,,480 mpdata,c,1,,530 mpdata,c,1,,675 mpdata,c,1,,670 mpdata,c,1,,660 mpdata,c,1,,780 mpdata,c,1,,820 mp,dens,1,7800 mp,alpx,1,1.78e-5 mptemp,,,,,,,, mptemp,1,25 mptemp,2,100 mptemp,3,200 mptemp,4,300 mptemp,5,400 mptemp,6,500 mptemp,7,600 mpdata,kxx,2,,176 mpdata,kxx,2,,180 mpdata,kxx,2,,184 mpdata,kxx,2,,188 mpdata,kxx,2,,192 mpdata,kxx,2,,198 mpdata,kxx,2,,200 mpdata,c,2,,728 mpdata,c,2,,795 mpdata,c,2,,879 mpdata,c,2,,963 mpdata,c,2,,1089 mpdata,c,2,,1290 mpdata,c,2,,1560 mp,dens,2,2700 mp,alpx,2,9.36e-6 |
