求助列车荷载加载问题!
各位前辈:我想对所见的钢轨模型在节点上加列车荷载,用matlab已经生成列车荷载矩阵。如下是我编的命令流:
/config,nres,10000
*set,t1,0.00039 !起始时间
*set,t2,3 !结束时间
*set,t3,0.00039 !时间间隔
amum=(t2-t1)/t3+1
*dim,nodel,array,91 !左边钢轨节点序列
*do, i,1,91,1
nodel(1)=i
*enddo
*dim,noder,array,91!右边处钢轨节点序列
*do, j,183,273,1
noder(1)=j
*enddo
*dim,shudingload,table,amum,3322,1, , , !读入节点力,单位是n
*tread,shudingload,E:\\nie\shudingload,txt,, !读取列车荷载路径,
/solu
ALPHAD,0.0999
BETAD,9.99E-05
*do,t,t1,t2,t3
time,t
nsubst,1 !指定一个荷载子步
*do,jj,1,91,1 !91层节点循环
f,nodel(jj),fz,shudingload(t,jj)
f,noder(jj),fz,shudingload(t,jj)
*enddo
acel,,9.8 !施加自重
allsel,all
solve
*enddo
finish
执行时警告没有读入文件,shudingload.txt为列车荷载力文件。请各位大侠指点!
