1. Platform for moving and positioning Target Spectometer without any groves in the floor Workshop – June 20 10 Cracow University of Technology Mechnical Design Group W. Czyżycki, M. Domagała, G. Filo, M. Hawryluk, E. Lisowski

2. The Target Spetometer without the platform The Target Spetometer without the platform 2

3. Target Spectometer with the moveable platform and Muon Filter, which is not moveable Target Spectometer with the moveable platform and Muon Filter, which is not moveable 3 Fudamental Muon Filter Target spectometer Platform Guide line

4. The construction of the platform includes standard long four I-beams HEB800 4 This construction of the platform give us three possibilities to movement: 1.on DELU air pads 2.Independly we can use special polymeric slippers without or with air pads 3.The Hilman Rollers- for this we need steel rails on the floor and lifting system for positioning hydraulic cylinder air pad slipper/support air supply hose

5. End positioning and setting the platform 5 roller guides end stop/positioner Guideline and hydraulic actuator can be removable – wth bolts) (V structure can be removable – with bolts)

6. View along z-axis 6 Floor level Sliders End stop positioner Muon Filter Platform Air Pads

7. Bottom view 7 air padsslippers/supports Hydraulic Jack Dipole Magnet Muon Filter length = 10980mm With=4900 mm

8. Air pads system Air pads system 8 Air pad pipe Each 1200mmx1200mm Lifting hight 40 mm

9. Izometric view Izometric view 9 Twenty plastic sliders under the platform 700mmx300mm Coeficient of the friction less than 0.08

10. Izometric view Izometric view 10 Removeable plastic sliders and air pads under platform

11. Positioning – guide line and fix points Positioning – guide line and fix points 11 End fix point Guide line with bolts at the floor

12. The construction with Hilman Rollers The construction with Hilman Rollers 12 It is posssible move Target Spectometer usinig four blocks of the Hilman Rollers. The Hilman Rollers could be located between I-beam so construction can be the same us for pads and sliders. It gives possibility to move only in one direction. The positiong x, z – direction will be huge challenge for this solution Rollers

13. Contact pressure on the floor 1.Air pads – 0.315 MPa 2.Plastic sliders – 0,857 MPa 3.Hilman Rollers – 11,837 MPa (Hilman Rollers pressure on floor by the rail)

14. FEM Analysis - shell model, constraints and load FEM Analysis - shell model, constraints and load 14 Mass of the target 300 ton, mass door 40 tons

15. FEM Analysis – von Mises stress FEM Analysis – von Mises stress 15 I-BEAM Von Mises Stress less than 100MPa

16. FEM Analysis - displacement FEM Analysis - displacement 16 Displacement magnitude less than 0.5 mm

17. Double DELU system 17 hose accessory, consisting of: 12 piece connecting hoses each 5 m long, (2pcs reserve) with two female quick connection couplings each 2 piece high flexible supply hose 30m long, diameter 2” with two female quick connection couplings each 2 piece air connection point 2" with external thread Air Consumption 8 m3/min for one segment, pressure 4 bar, lifting 40 mm Eight or ten pads max load 400 tones The pressure will be controled in each path

18. Summary Air pads platform with plastic sliders Advantages: 1.Give possibility to move in three direction x,y,z 2.No deformation of the structure and low stress 3.Low contact pressure on floor 4.We don’t need to prepare channels in floor to mount (precisely machined) rails. Guidance for air pad platform can be mounted on floor. 5.We need the air pads only during moving, after that you can use the pads to move another load 6.It is possible to exchange plastic sliders made of plastic into steel ones if the Target Spectometer not move long time.
