CCA Passive Vibration Damper
Keywords: CCA, vibration, damper
This paper summarizes the approach used to design and implement elastomeric dampers between a Circuit Card Assembly (CCA) and a chassis subassembly. The dampers were added to reduce high CCA vibration levels experienced during random vibration testing. The paper addresses damper-level design, analysis, build and test issues, and assembly-level analysis and testing results.
