High Deflection Mounts

High Deflection Mounts are named to describe the relative deflection potential of the mount under load. High deflection mounts are typically used for shock attenuation applications. Although they will function as good vibration isolators, the size of the mounts do not make them efficient for vibration isolation applications alone. The elastomeric resilient element is designed to buckle under load for best attenuation of shock input energy. Many of the Barry Controls High Deflection Mounts are designed around Mil-Specs that deal specifically with shock events so their performance capabilities, relative to those specs, are well known and described in the published data. This makes selection from these mounts relatively easy in terms of what will work and what won’t work.

It is important to verify if a non-snub condition or a soft snub condition exists when selecting from these mounts as a hard snub will most likely amplify the input energy causing damage to the payload. Additionally, none of these mounts are integrally fail-safe and require a Barry Controls safety strap designed for the specific mount to ensure positive capture of the payload in the unlikely event of failure of the resilient element. Some installations require an electrical grounding path across the isolator that can be accomplished with the same strap or special grounding cable (available from AEK). Barry Controls High Deflection Mounts perform best when supporting the primary static load axially through the mount.
