CLIC Two-Beam Module MB Girder Boundary Conditions
14 February 2011
Input from D. Gudkov
Cases: I. Case 1 (blue) –Sliding –
1 DoF along the z-axis (longitudinal dilatation of ACS) 0 DoF along the y-axis 0 DoF along the x-axis
II. 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)
III. Case 3 (green) –Fixation– 0 DoF along the z-axis 0 DoF along the y-axis 0 DoF along the x-axis

Case Study – Subassemblies for analysis
Case Study: i. U-clamp baseline material: Aluminum Alloy;ii. Forces introduced in the model:
a. Gravity (component weight);b. Thermal loading for the ACS (20-40°C);c. Vacuum: Pressure Load (ΔP = 1 bar).
Case 3: Intermediate (fixed) U-clamp
Case 1: Extremity (sliding) U-clamp
Case 2: Middle (sliding) U-clamp
