The friction spring damper is an all-metal structure. It uses the friction between the annular metal spring sheets. The inner ring and the outer ring slide against each other on the conical surface. Each ring undergoes elastic deformation, the outer ring is stretched, and the inner ring is compressed. A large amount of energy is dissipated during the friction stroke, and it has excellent damping energy dissipation performance.
Compared with traditional hydraulic dampers, the friction spring damper adopts the all-metal friction principle, eliminates hydraulic oil, effectively avoids the risk of oil leakage, greatly improves environmental adaptability, and is resistant to high temperature, low temperature, corrosion and other harsh environments. At the same time, it has extremely high energy efficiency and is widely used in the field of military, industrial and building bridge structure vibration reduction.
High energy dissipation capacity, light weight, small size
The performance curve can be adjusted by the number of ring spring units.
Linear mechanical performance curve
Overload protection in the stop (pressed or pulled) position
High vibration reduction capacity
Force vs. travel curve is not affected by loading speed, not affected by temperature
Maintenance-free during the whole life cycle
Multiple groups of friction springs can be arranged in parallel to withstand higher forces, or in series to obtain a larger spring travel
The storage period is 5 years and the service life is 10 to 30 years.
