Material Properties and Vibration Isolation

General information on Sylomer®

Sylomer® is a special PU elastomer manufactured by Getzner, which features a celled, compact form and is used in a wide range of applications in the construction and mechanical engineering industries. In most cases, Sylomer® is used as a compression-loaded elastic support element. The characteristics of the elastic support can be adjusted to the structure, construction method and load requirements by selecting the specific type of Sylomer®, the load-bearing area and the thickness.

Sylomer® materials are available as a continuous roll and are particularly well suited as flat, elastic layers. Above and beyond this, engineered moulded parts made of Sylomer® are also available.

For specific applications, special types can be manufactured with precisely defined stiffness. The material’s fine celled structure provides the necessary deformation volume under static and dynamic loads. As a result, elastic bearings with full-surface load transmission are possible. This offers major engineering and economic advantages, especially in the construction industry.

Quasi-static load deflection curve

Fig. 2 shows the typical pattern of the load deflection curve for Sylomer® under compression load.

In the lower load ranges, there is a linear relationship between tension and deformation. For elastic bearings, the permanent static load should fall in this range. The load range is specified in the individual data sheets.

After the linear load range, the load deflection curve moves on a degressive path; the material reacts to additional static and dynamic loads in a particularly “soft” manner, thus allowing for highly effective vibration isolation. In the data sheets, the area of the deflection
curve in which a high degree of efficiency is achieved with a relatively small degree of spring deflection, marked with the lighter shading in the diagram.

Machine Foundation Isolation

Large industrial machines generate dynamic vibrations that can cause damage, affect nearby equipment, and disturb people with noise. Foundation isolation, designed away from the machine’s operating frequency, reduces amplitudes and velocities.

Getzner offers customized foundation isolation for various types of machines like pumps, compressors, turbines, machine tools and mills. The elastomer materials Sylomer® and Sylodyn® are located under the machine foundation on top of the subgrade or alternatively on lean concrete.

Your benefits with solutions from Getzner

✓ Material selection tailored to the machine investigated

✓ Defined elastic material properties which can be incorporated in any calculation

✓ Maintenance free products

✓ Fulfillment of amplitude requirements given by machine manufacturers, codes or standards.

✓ Services during material installation – like supervision

Making the subgrade predictable - protect the machine

EPCs (Engineering, procurement and construction), construction companies and engineering firms responsible for foundation design are facing special challenges related to the subgrade. Making the subgrade capable of bearing the weight of foundation and machinery is an obvious requirement, but also the dynamic properties of the subgrade cannot be neglected in the dynamic foundation design. Getzner’s solution is the answer making a cost and time efficient foundation design independent of the dynamic subgrade properties possible.

Protect the surrounding - vibration mitigation

Machines generate vibrations, which are introduced in their vicinity, leading to disturbance, damage and interruption of plant operations. Control rooms and equipment, the machine building itself but also offices are exposed to unwanted vibrations.

Passive isolation - vibration mitigation

Machine borne vibrations are typical to a manufacturing environment. Implementing a machine foundation isolation reduces the risk of negative effects of vibrations on the operability of the machine, increases its precision and gives the user additional flexibility where to place the machines.
