Vibration isolation VIBRAX® – Elastomeric bearings Vibration-isolating bearings

Vibration isolation Applications and key data General Structural positioning of the bearings VIBRAX®DAMP C is a profiled unreinforced deformation bearing with special properties in relation to structure-borne sound insulation and vibration isolation. If an elastomeric bearing is vertically loaded, it becomes compressed and its sidewalls bulge outwards. The positioning of the bearing must allow this bulging, and ensure that the bulged bearing still rests completely within the reinforced area of the substructure (see Figure 1). At maximum loading, transverse deformation of r ≤ 10 mm can be expected....

Vibration isolation Design criteria Compression curves 4 The load-deformation behaviour of the bearing is only marginally influenced by the roughness of the connecting surface. Very rough surfaces can allow larger deflections than smooth surfaces, because the material is pressed into the unevenness of the surface at high pressure. Dynamic stiffness depends on pressure Dynamic stiffness [N/mm3] depending on pressure - for a disturbing frequency of 50 Hz and 100 Hz

Vibration isolation Delivery, installation and tendering Delivery format Suggested text for tender requests VIBRAX®DAMP C is available as a 1200 x 1200 mm panel, with a thickness of 12 mm. In addition to full panels, tailored pieces, with pre-drilled holes according to customer specifications, can also be supplied on request. Supply and installation of unreinforced sound insulation and deformation bearings, on flat, firm surface Range of application as optimal sound insulation: 1 to 4 N/mm2 Before laying of VIBRAX®DAMP C, the surface on which it is to be laid must be checked for flatness.
