  1. Preliminary Mechanical Analysis of the ILC TPC M. CARTY, D. ATTIE, P. COLAS, M. RIALLOT (CEA Saclay) DESY - September 22, 2009 M. CARTY - PMA of the ILC TPC

  2. Outline • Structure Configuration • PCB Analysis • TPC Analysis • Perspectives M. CARTY - PMA of the ILC TPC

  3. Structure Version 1 (2 x 84 PCB) - 2 x 12 x PCB1 - 2 x 18 x PCB2 - 2 x 24 x PCB3 - 2 x 30 x PCB4 4,6 m Version 2 (2 x 65 PCB) - 2 x 15 x PCB1 - 2 x 20 x PCB2 - 2 x 30x PCB3 Ø 3,6 m M. CARTY - PMA of the ILC TPC

  4. PCB Analysis - Hypothesis Loads : ∆P = 10 mbar Material : G11 (TBC) E = 24 000 MPa ρ = 1 850 kg/m3 ν = 0.15 Ri Version 1 – 4 wheel p Re e α Version 2 - 3 wheel M. CARTY - PMA of the ILC TPC

  5. PCB Analysis - Results Version 1 – 4 wheel Better from mechanical (deformation) point of view Version 2 – 3 wheel M. CARTY - PMA of the ILC TPC

  6. TPC Analysis - Hypothesis Size : Ø3,6m x 4,6m Weigth : WEB V1 => 2 x 370 kg (for Aluminium) WEB V2 => 2 x 345 kg (for Aluminium) PCB => 2 x 44 kg (TBC) Cage => 265 kg (TBD) Loads : Standard Earth Gravity Case 1 => ∆P = 0 mbar Case 2 => ∆P = 10 mbar (TBC) Material : WEB => Aluminium Alloy (TBC) E = 71 000 MPa ρ = 2 770 kg/m3 ν = 0.33 TPC => Composite (TBD) E = ??? MPa ρ = ??? kg/m3 ν = ??? 4,6 m Ø 3,6 m M. CARTY - PMA of the ILC TPC

  7. Evaluation of the TPC Material TPC => Composite (TBD) Ep = 25 mm E = 1 500 MPa ρ = 172 kg/m3 ν = 0.3 M. CARTY - PMA of the ILC TPC

  8. TPC Support 4 possible configurations Case 1 Case 2 Case 3 Case 4 M. CARTY - PMA of the ILC TPC

  9. TPC V1 - ∆P= 0 – Results Case 2 Case 1 Case 4 Case 3 M. CARTY - PMA of the ILC TPC

  10. TPC V1 - ∆P= 10 – Results Case 1 Case 2 Case 4 Case 3 M. CARTY - PMA of the ILC TPC

  11. TPC V1 vs V2 Déformation V1 - ∆P = 0 mbar Déformation V2 - ∆P = 0 mbar M. CARTY - PMA of the ILC TPC

  12. For the future Evaluation more precise of the Cage material (sample, measure) Simulation with composite material (carbon fiber) for the WEB Thermo-mechanical simulation Other configuration ? M. CARTY - PMA of the ILC TPC
