Component Vibration Mitigation

When a complete satellite is not protected by one of CSA's SoftRide systems, individual components on the spacecraft may experience excessive vibration during launch. Other components within launch vehicles are also subjected to high vibration environments. Vibration isolation systems are an effective means of reducing harmful component vibration. For components within launch vehicles, the high vibration environment is often combined with a requirement to conduct heat away from avionics components that generate excess heat. Convective cooling is often not sufficient.

CSA has developed a family of products based on the need in space vehicles and elsewhere for simultaneous vibration isolation and heat conduction. CSA has introduced materials having new and unique formulations with an order of magnitude higher thermal conductivity than today's materials of similar stiffness. This enables appreciable heat conduction with nominal temperature increases to isolated packages. Traditionally, the formulation of nearly all elastomeric vibration isolators creates heavy coupling between their loss factors and the rate of change in their storage moduli. High loss factors result in a strongly temperature-dependent shift in the suspension frequencies of an isolated element. New compounds introduced by CSA address this limitation.

CSA has developed specialized vibration isolation and damping systems for component vibration mitigation since the company's founding. For applications not requiring the superior heat conduction of the recently developed isolators, CSA offers custom designs for large ranges in suspension frequency, damping, and payload mass properties.
