Trelleborg's Novibra® division and Metalastik® have joined forces to become Trel- leborg Industrial AVS. A world leader in the design and manufacture of rubber to metal bonded components for antivibration applications and suspension systems used in rail, marine, industrial and civil engineering applications. Our strength is that we can offer a wide range of isolators in combination with the specialised expertise that is needed to achieve a total solution. We use data-based surveillance software, conduct tests, and provide full technical support. Trelleborg Industrial AVS employs...

Metaxentric™ Bushes Spherilastik™ Bearings Similar to conventional Ultra Duty Bushes but with inner and outer sleeves offset radially. This feature provides a greater rubber thickness and hence increased flexibility in the normal direction of loading while maintaining control in other modes and still allowing torsional movement. Typical uses include traction and braking reaction rods for rail, road and off road vehicles, hydraulic damper fixings and other applications where a high duty bearing of compact size is required. For vehicle suspension, pivot arms and all types of mechanical...

From R & D to finished product Being a member of the Trelleborg Group enables Trelleborg Industrial AVS to be in a position of full control of the complete production process and all vital raw materials. The Trelleborg Group has its own rubber mixing depart- ments and laboratories with complete test equipment for measurements of raw materials and finished products. Our laboratories continuously measure and control specifica- tions of the raw material and finished products. Trelleborg Industrial AVS has an R&D department, production facili- ties in the UK and Sweden, and follows the product...

Trelleborg Industrial AVS - Vibration technology VIBRATION CAUSES STRUCTURE-BORNE NOISE Vibration is generated by all kinds of machinery particu- larly those with rotating or reciprocating movements. Solidly mounted, these generated motions would be transmitted directly to the foundations giving rise to ir- ritating noise to the immediate surroundings where the Noise may also occur in areas some distance away trans- mitted through the structure. This is normally referred to as "structure-borne noise" (structural noise). In addi- tion to noise, the creation of vibration can cause serious...

THE PROPERTIES OF RUBBER MAKES IT PARTICULARLY SUITABLE AS A SPRING Vibration isolation is based on installing machinery on springs or resilient material of known stiffness. The types of spring material which are used most often are rubber and steel. Another alternative is air springs. Rubber has high load bearing capacity with an ability to accommodate overload conditions without the cata- strophic failures associated with steel and other materials. It can carry complex loadings more easily and economi- cally than other alternatives. The bonding of rubber to a rigid material creates a...

RUBBER AS AN ENGINEERING MATERIAL Compared with other engineering materials, rubber is very ductile. In some cases, the elongation may be higher than 1000%, and by far the highest proportion of this strain is elastic. Metals, on the other hand, have very small strains below the elastic limit. Compared with met- als, the tensile strength of rubber is low. The maximum level that can be achieved with rubber is 25-30 MPa. However, because of the high strain, rubber has a very large work absorption capacity compared with the best If a material is subjected to a load below the elastic limit, the...

Table 1. Typical properties for rubber compounds used in antivibration mountings. SPRING COEFFICIENTS A rubber spring has different charactistics for static and dynamic conditions. A constant load causes a deflection, and the inclination/deflection gives the static spring co- efficient. When the spring from equilibrium is loaded with a dynamic force, the response is a higher spring Static Stiffness The stiffness of a spring is a measure of applied force (P) against a resulting Deflection (X). Measurements taken at a continuous feed rate (usually in the order of lmm/sec velocity) provide...
