Noise and vibration abatement composite laminated shim LAMECO

OVERVIEW

Any mechanical assembly in working order generates vibrations that are source of harmful frequencies.
To bring an answer to this main drawback, Daniel GASTEL designed and patented a new laminated product called SILENTLINE®.
SILENTLINE® is a composite of metal and synthetic material, which has the immense advantage of dispersing - therefore dampen - frequency transmission. And this to a very large extent. Product picture here.

ADVANTAGES

I. The cost of SILENTLINE® laminated shims is practically equivalent to that of shims made of other laminated materials. So there is no economic obstacle to their use.

II. The mechanical characteristics of laminated shims are improved with this material.
CETIM tested two probes, both in 2 mn thickness :
a) The first one, conventional, entirely consisting of peelable metal leaves: achieved Vickers value = 440 MPA.
b) The second one manufactured in the new material : achieved Vickers value = 510 MPA.

III. SILENTLINE® laminated shims which thus require less maintenance and are less subject to wear.

PERFORMANCES

Tests carried out by CETIM on this new material show its capacity to tone down - in a spectacular way - the two consequences of a harmful frequency emission :
- Absorption or dampening and dispersion of 45 to 50 % of the amplitude
- Reduction by 50 to 55 % of the emission duration.

This is therefore a high performance material.
