Leaf Spring prototype preparation M.Lenti

Reminder Piet’s proposal: two dowels inserted into two mirror holes (vertical alignment); mirror weight as counterbalance Two leaf springs (horizontal alignment); pretensioning in nominal “zero” position Piezo actuators out of particles acceptance 14/07/20102M.Lenti

Piet’s proposal 14/07/20103M.Lenti

Carassiti drawings Delivered on june 3 Original (Piet’s) approach: center of horizontal rotation “on” the mirror “inverted” approach: center of horizontal rotation “far” from the mirror Both taken in consideration 14/07/20104M.Lenti

Leaf spring Support 14/07/20105M.Lenti

Aluminum clamper 14/07/20106M.Lenti

Aluminium Dowel 14/07/20107M.Lenti

Aluminium Leaf 14/07/20108M.Lenti Thickness: 0.5 mm Height: 200 mm

Aluminium Support 14/07/20109M.Lenti

Dowel Aluminium Plate 14/07/201010M.Lenti

Piet’s correction June 17 14/07/201011M.Lenti

New drawing 14/07/2010M.Lenti12 F.Maletta Can be mounted in with the “original” or “inverted” approach

Prototype situation Aluminium raw material arrived last week (!!!) Executive drawings ready Mechanical worshop in Florence ready for working Hope to have the pieces machined by next week 14/07/201013M.Lenti

Resonances Estimated by Vito Glass: very low, just above 0 Hz Support structure: 1° resonance around 7.5 Hz 14/07/2010M.Lenti14

Conclusions A lot of time lost for material procurement Hope to have some results late in july… 14/07/2010M.Lenti15
