请问这个分段函数载荷怎么加载?
形如下列形式的载荷如何加载:0~2s,F=20000
2~3s,F=0
3~4s,F=30000sin(6t)
这样对吗?请大家指教
fk,1417,fx,200000
time,2
kbc,1
nsubst,5
allset,all
lswrite,1
fk,1417,fx,0
time,3
kbc,1
nsubst,5
allset,all
lswrite,2
lssolve,1,2,1
*dim,sine,,20,2
*do,i,1,20
t=3+0.05*i
sine(i,1)=t
sine(i,2)=3e5*sin(6*t)
*enddo
kbc,0
*do,i,1,20
time,sine(i,1)
nsubst,5,0,0
fk,1417,fx,sine(i,2)
solve
*enddo
finish
