Two-stage Isolation

small reaction wheel

海角社区鈥檚 two-stage isolation systems are based听upon the flight proven technologies of SoftRide听OmniFlex and ShockWave isolators. The softer听first stage is for small on-orbit displacements听and low frequency isolation. The second stage is听stiff and highly damped to protect the more听delicate first stage isolators during launch. Both听stages are packaged together into a single听isolation module.

Overview

The first stage is equipped with OmniFlex isolators听which utilize a metallic load path flexure in听parallel with viscoelastic damping. In a zero-G field the payload rides on the systems first听stage. The second stage is made up of ShockWave isolators which provides highly damped听launch isolation by limiting deflection of the module during launch. The second stage听performs very much like a linear isolation system and does not produce high-frequency听responses. Second stage has the added benefit of providing attenuation for launch听vibration and shock events compared to a hard-mounted or launch locked configuration.
