  3. CLIC Two-Beam Module MB Girder • Boundary Conditions S1 S2 S3 S4 AMB BMB CMB DMB EMB MB type 0 I II Model Boundary Conditions • 3D layout with colored clamp cases (explanatory slide following): • Case 1 (blue): Sliding • Case 2 (red): Sliding • Case 3 (green): Fixation Input from D. Gudkov Nick Gazis, CERN-BE/RF & NTU-Athens

  4. CLIC Two-Beam Module MB Girder • Boundary Conditions • Cases: • Case 1 (blue) –Sliding– • 1 DoF along the z-axis (longitudinal dilatation of ACS) • 0 DoF along the y-axis • 0 DoFalong the x-axis • Case 2 (red) –Sliding– • 1 DoF along the z-axis (longitudinal dilatation of ACS) • 0 DoF along the y-axis • 0 DoF along the x-axis • (only layout difference between cases 1 & 2, same principle of the boundary conditions) • Case 3(green) –Fixation– • 0 DoF along the z-axis • 0 DoF along the y-axis • 0 DoF along the x-axis Input from D. Gudkov Nick Gazis, CERN-BE/RF & NTU-Athens

  5. Case Study – Subassemblies for analysis Case 2: Middle (sliding) U-clamp Case 1: Extremity (sliding) U-clamp • Case Study: • U-clamp baseline material: Aluminum Alloy; • Forces introduced in the model: • Gravity (component weight); • Thermal loading for the ACS (20-40°C); • Vacuum: Pressure Load (ΔP = 1 bar). Input from A. Samoshkin Case 3: Intermediate (fixed) U-clamp Nick Gazis, CERN-BE/RF & NTU-Athens

  6. Case Study – Meshed Models Case 1: Extremity (sliding) U-clamp Case 2: Middle (sliding) U-clamp Case 3: Intermediate (fixed) U-clamp Nick Gazis, CERN-BE/RF & NTU-Athens

  7. Case 1: Extremity (Sliding) U-Clamp Aluminum 6082 Max Stress < 20 MPa Aluminum 6082 Max Deformation <45 μm Nick Gazis, CERN-BE/RF & NTU-Athens

  8. Case 2: Middle (Sliding) U-Clamp Aluminum 6082 Max Stress <15 MPa Aluminum 6082 Max Deformation <45 μm Nick Gazis, CERN-BE/RF & NTU-Athens

  9. Case 3: Intermediate (Fixed) U-Clamp Aluminum 6082 Max Stress < 11 MPa Aluminum 6082 Max Deformation <55 μm Nick Gazis, CERN-BE/RF & NTU-Athens

  10. Summary & Future Steps • Summary of Accomplished Tasks: • MB U-clamps modelization; • Study of boundary conditions; • MB U-clamps and MB RF-components simplification; • MB U-clamps simulation. • Future Tasks & Testing: • MB U-clamps optimization (under consideration); • DB U-clamps modelization; • DB U-clamps simulation; • DB U-clamps (under consideration).
