  1. Update on the DB Girders FE Analyses Nick Gazis, CERN-BE/RF & NTU-Athens

  2. DB Quad Weight Approximations Nick Gazis, CERN-BE/RF & NTU-Athens

  3. FE Analysis: Boostec Girder Boostec girder Deformation ≤ 17 μm Boostec girder eigenfrequency: 37.7 Hz Nick Gazis, CERN-BE/RF & NTU-Athens

  4. FE Analysis: Epucret Girder Epucret girder Deformation ≤ 18.7 μm Epucret girder eigenfrequency: 61.5 Hz Nick Gazis, CERN-BE/RF & NTU-Athens

  5. Summary & Future Steps • Future Tasks: • Update of the CLIC module weight estimation (EDMS doc 1009300) A B C • Concern - Possible Future Task: • Epucret top reference surfaces could be affected by the increased weight? • A rupture investigation for fine ceramics (like SiC, Epument) would need thorough time-consuming simulation with fatigue time and dedicated fracture mechanics background for a specific material. Comments are always welcome! Nick Gazis, CERN-BE/RF & NTU-Athens

  7. Weight Estimation of the CLIC-Module [Type 0] Supplementary Slide EDMS 1009300 * An average SiC density value is taken for estimation. It might change depending on particular material properties. Nick Gazis, CERN-BE/RF & NTU-Athens

  8. CLIC-Module MB & DB Baseline Girder Technical Specification: EDMS 1061067 Supplementary Slide CLIC Type 0 Supporting System (space reservation) • Girder Baseline Configuration (Nov 2009): • Max. Vertical & Lateral Deformation at 10μm • Max. Girder Weight at 240kg • Max. Girder Length of 2m • Max. Load on top of the Girder 400kg/m (distributed weight) • Rectangular Space Reservation of External Dimensions of [320*150]mm • References Surfaces (as presented in color surfaces with possibility of tolerancing ≤ 20 μm) Baseline Configuration with Reference Surfaces DB-quad: Non-concentrated weight of comparable order of magnitude 350 mm 150 mm 150 mm 350 mm • Handling Zones Nick Gazis, CERN-BE/RF & NTU-Athens
