The main typical characteristics of the JARRET friction damper are :

• Low sensitivity of the friction force at the working temperature (-200°C / + 200°C)
• Low sensitivity at the working velocity (F " C*V a, a"0.2 at RT and a"0.01 at -196°C)
• Capability to work under very short stroke (from some hundredths mm)
• Width frequency range, from 0 to a few hundred Hz,
• Capability to work under high working velocity (up to 100 m/s)
• No pressure, no risk of explosion due to a high pressure
• No fluid, no risk of leakage
• Low mass

Typical applications

• Damping of micro-vibrations of pipes.
• Damping under cryogenic ambiance.
• Space applications (damping of stabilizing boom, tanks…).
• Applications with high velocity impact (e.g. pyrotechnic test bench)
