Flexible support ring maintaining the link between pipe and structure providing vibration isolation and protection against shock.
Pipe isolators
Natural frequencies under nominal load:
– axial: 10 to 30 Hz
– radial: 15 to 40 Hz
Maximum displacement in axial shock: ± 5 mm

Strafluid Hydraulic mountings
A hydraulic suspension can at the same time provide a low frequency damping function.
The progress in motor vehicle design and increased demand for comfort both in terms of vibration and sound-proofing has resulted inincreasingly demanding specifications for suspension systems.
PAULSTRA hydraulic mountings use an elastomer support device combined with an hydraulic system. The hydraulic system acts differentially and specifically in relation to the frequency range and the type of vibrational excitation incurred.
These mountings, due to a total integration of all components, are still compatible with standard sizes and are as easy to fit as conventional mountings.

Flexible mountings for low loads MN 50
They allow to limit the reactions at the moment of the shock.
The permitted deflection (40 to 50 mm) of the suspended mass in relation to the mounting base limits reaction under shock.No efficient vibration protection is offerred during shock.

Laminated mountings
These assemblies can withstand high compression loads.
These assemblies can withstand high compression loads (along Oz): up to1,000 tons/sq.meter.
They can absorb shear deformation (along Ox and Oy) of 50 to 100% of their height.
Cylindrical or annular type assemblies can also withstand torsional displacement around axis Oz.
In rotation around axes Oy and Ox, these mountings enable angular or low amplitude rotation errors (approximately 1°).

Anti-Vibration mountings for avionics and electronics
Applications range from vibration isolation to shock-protection of electronic apparatus.
Models are available in different elastomers: silicon, fireproofed silicon, fluorosilicon or neoprene, to meet the requirements of the main aeronautics standards (FAR 25 – AIR 7304 – MIL STD 810 – C 172 C -MAR 508 s.o.).
Covering a natural frequency range of 15 to 50 Hz, their applications range from vibration isolation to shock-protection of electronic apparatus and also aircraft fuselage and helicopter cockpit mountings.
