Requirements
Jul 31, 20204 Mitchell Kane | Transport Frame | 650 MHz HB CM Proto FDR
• Transport the HB650 cryomodule in its transport configuration from
Daresbury Laboratory, UK to FNAL, USA
• Mitigate logistical drops, shocks, and vibrations
• Enable the cryomodule to be lifted through the frame
• Resist transportation loads, e.g., braking, cornering, accelerating
• Ensure adequate clearance between module and frame
• Protection from environmental effects and restricting access

Analysis
Drop
Jul 31, 202012 Mitchell Kane | Transport Frame | 650 MHz HB CM Proto FDR
• MIL-STD-810H specifies a
0.46m drop height for
general items
• Exceptions permitted
for large, complex
items
• Specification limits pCM
shocks to 2.5g vertically
• 0.24m achievable at 1.9g
with chosen isolators
• 0.31m achievable at 4.4g
with alternative isolators
