Hello Wang,

welcome :-)

>  I don't know what is wrong

actually nothing is wrong, your code works as expected.
After O.run(10000,True), try

for b in O.bodies: print b.state.displ()

You will see, that the particles did move, but only little and the displacement is not visible. This is probably due to simulation setup (forces magnitude, stifnesses, sizes etc.)
In Yade GUI at "display" tab, you can set dispScale to magnify displacement. I set the three values to 1000 and clearly see the displacement.

cheers
Jan
