3/2 directional valve with BAO0021/22

Hello,

I am stucked with parametrization of a 3/2 directional valve.

I am handling the sections with at least 2 components BAO0021/22 (with file name)

The valve is hold in position with 2 springs (one at each side) and can move untill 12.5mm in one side and 10.5mm on the other side

So I started to describe the displacement from -12.5mm till +10.5mm, centered at 0. But as soon as the displacement enters in "negative" values, the BAO components  (both oriented in the same direction) don't give the right section (according to the file)

So I tried to describe the displacement from 0 till 23mm, centered at 12.5mm. Here the section are ok (I had to fix the displacement values in the files), but I am unable to hold the mass at 12.5mm

Any tipp to describe properly the motion/section?

Hello,

 

Would it be possible for you to share the plots that you obtained for both cases either for the displacements and the sections?

 

Thank you.

Hello @NLaviolette,
I could fix my issue
I kept the files with underlaps >0 and I correct them with the parameter x0 (underlap corresponding to zero displacement)

Everything is now ok
