Presentation Transcript

  1. ANSYS simulations for the Drive Beam U-clamps* • * continuation of EDMS doc 1133226: • “MB U-clamps FEA” Nick Gazis, CERN-BE/RF & NTU-Athens

  2. Index • Boundary Conditions • Case Study • Cases • Results • Summary & Future Steps Nick Gazis, CERN-BE/RF & NTU-Athens

  3. CLIC Two-Beam Module DB Girder • Boundary Conditions P1 P2 P3 P4 ADB BDB CDB Q1DB DDB EDB FDB Q2DB DB type 0 II I Model Boundary Conditions • 3D layout with colored clamp cases (explanatory slide following): • Case 1 (blue): Sliding • Case 2 (green): Fixation • Case 3 (red): Sliding (Analysis simplified model) Nick Gazis, CERN-BE/RF & NTU-Athens

  4. CLIC Two-Beam Module DB Girder • Boundary Conditions for the U-clamps • Cases : • Case 1* (blue) –Sliding– • 1 DoF along the z-axis • (longitudinal dilatation of PETS) • 0 DoF along the y-axis • 0 DoF along the x-axis • Case 2 (green) –Fixation– • 0 DoF along the z-axis • 0 DoF along the y-axis • 0 DoF along the x-axis • Case 3* (red) –Sliding– • 1 DoF along the z-axis • (longitudinal dilatation of PETS) • 0 DoF along the y-axis • 0 DoF along the x-axis • *[only layout difference between cases 1 & 3, same principle for the boundary conditions] • Case Study: • U-clamp baseline material: Aluminum Alloy; • Boundary Conditions: • Gravity; • Vacuum: Pressure Load • (ΔP=1 bar); • Thermal loading for the PETS (20-40°C). Input from D. Gudkov (Analysis simplified model) Nick Gazis, CERN-BE/RF & NTU-Athens

  5. Case Study – Models & Cases Meshed Model U-clamps models Case 2: Fixation U-clamp Case 1: Sliding U-clamp Case 3: Sliding U-clamp Nick Gazis, CERN-BE/RF & NTU-Athens

  6. Results – Deformations Case 2: Fixation U-clamp Case 3: Sliding U-clamp Case 1: Sliding U-clamp Nick Gazis, CERN-BE/RF & NTU-Athens

  7. Results – Stresses Case 2: Fixation U-clamp Case 3: Sliding U-clamp Case 1: Sliding U-clamp Nick Gazis, CERN-BE/RF & NTU-Athens

  8. Summary & Future Steps • Summary of Accomplished Tasks: • Study of boundary conditions for MB and DB; • MB & DB U-clamps modelization; • MB & DB U-clamps and MB & DB RF-components simplification; • MB & DB U-clamps simulation. • Future Tasks & Testing: • DB U-clamps optimization (if needed); • Simulation of the overall subassembly of the DB components (with the fixed DB-quads supports and the interconnecting bellows).
