Sylomer® Aluminium
Vibration Damper
Floating Floors for Rolling Stock

DesignHigh-quality anodised aluminium profile with a wall thickness of 2 mm. Its construction consists of an upper andlower profile that are clipped together. Sylomer® strips
are used as elastic inserts and for vibration suppression.
The profiles are able to absorb the forces that occur inthe event of a collision. The two thin Sylomer® inserts
also serve to transfer the tensile forces upwards. They
prevent the aluminium parts from colliding when the train
brakes and in the event of emergency braking. The standard length of the profiles is 1.5 metres. The Sylomer®
inserts are individually adapted to the working loads ofeach train.
The hollow space in the upper profile allows floor panels
to be fastened with screws. The profile is affixed to thebare floor of the carriage by screwing the side tabs. A
groove is provided as a drilling aid. Thanks to the cooperation with SAPA — the world leading manufacturer ofaluminium profiles — the design can be adapted to thecustomer's requirements as necessary.

Area of application
Sylomer® Aluminium vibration dampers are used for thebearing of floors in trains and ships as well as for machineengineering applications. The elastic Sylomer® inserts
provide effective vibration decoupling and lead to a dramatic reduction in secondary airborne noise. All components mounted on them (train interiors or machines) are
subjected to fewer vibrations, which extends their service
life. The low installation height of 30 mm aids lightweight
construction and the planning of low floor structures.

Customer beneﬁts— Effective isolation and decoupling of vibrations— Less noise in rail vehicles— Simple screw-mounting reduces installation
time and costs— Elastic Sylomer® inserts help to offset tolerances
during installation— Sylomer® Aluminium vibration dampers can be
flexibly adapted to the customer's requirements— Constant material properties over the long term —no maintenance required

Advantages— No brittleness of the Sylomer® inserts(free from softeners)— Various types for different working loads— Flammability in accordance with DIN EN 45545-2— Low installation height of 30 mm— Aluminium profile designed for maximum
loads in a rear-end collision— Electrically insulating— Resistant to oils and greases— Total weight per metre approx. 3 kg

The natural frequencies can be controlled by the profile distances and can therefore
be individually adapted. The maximum deflection stated is based on the maximum
line load when the maximum permissible weight is reached.
