THE SOLUTION Machinery, which by virtue of its design has reciprocating or rotating parts, creates vibration to some degree through imbalance of the moving parts. This vibration produced by a machine leads to different problems, such as a reduction in the machine’s useful life through part wear, plus the transmission of this vibration to other non-insulated adjacent structures, giving rise to problems of noise and vibration transmission. For more than 45 years, AMC MECANOCAUCHO® has been developing the “AMC MECANOCAUCHO®” range of rubbermetal anti-vibration supports which can solve problems like...

ENGINEERING ENGINEERING One degree of freedom calculation Anti-vibration calculation with more than one degree of freedom. AMC MECANOCAUCHO® calculates anti-vibration solutions by taking into account data such as weight, mount positions, type of machine, Center of Gravity, frequency of excitation, etc...

After studying client specific needs for the application and the isolation performance required, AMC MECANOCAUCHO® can produce a new design if standard products are not suitable. Stress analysis by nonlinear FEM Structural analysis Initial concept Final Concept

3. Test and dynamic characterisation AMC MECANOCAUCHO® can offer customers a wealth of experience and know how in measuring noise and vibration to effect optimun solutions to those problems. AMC MECANOCAUCHO® provides its customers with all its experience and know-how in measuring vibrations and noise in the field so as to reduce machine-produced emissions of noise and vibrations.

ANTI-VIBRATION TECHNIQUES 1.-ABC AT A GLANCE MASS SPRING SYSTEM A mass spring system may be represented by a mass “M”, excited by a force ”F” and supported on an elastic stiffness element “K” with a dampering factor “C”. The frequency of the mass spring system is equal to: Where Cc is the critical damping and the damping coefficient. For this system we obtain a transmissibility T and a magnification factor A: figure 3 K (N/m) M (Kg.) Fo (Hz) C (Ns/m) The effectiveness of the suspension may be measured by transmissibility, i.e. by the force which is transmitted by the machine to the ground or...

ANTI-VIBRATION MOUNTS If the frequency of excitation is times less the natural frequency, transmissibility is greater than one, then the force transmitted is greater than the excitation force, there is magnification of the vibrations. When we work in this area, the existing damping in the system is important. The greater the latter, the smaller the magnification of the vibrations will be. If the frequency of excitation is times greater than the natural frequency, transmissibility is less than one, or in other words the force transmitted is less than the force originated in the system, then we...

ANTI-VIBRATION TECHNIQUES 1.-DYNAMIC TESTING MACHINE Dynamic stiffness can only be established by measurement on a dynamic test bench. Similarly, the damping coefficients of compounds are further values that can be measured with this type of machines. One concept that must be taken into account when designing an anti-vibration mount is its durability. A dynamic testing machine allows us to conduct fatigue tests that reproduce the real working conditions of the part so that its useful life can thus be predicted accurately. 2.- ANALYSIS OF SYSTEMS OF MORE THAN ONE DEGREE OF FREEDOM In actual fact,...

ANTI-VIBRATION MOUNTS GENERAL CHARACTERISTICS OF ELASTOMERS NATURAL RUBBER Natural rubber is used in the manufacture of elastomers with high elasticity and tear strength. It is a strong material with excellent abrasion resistance. Among all the rubber families, natural rubber offers the best resistance to mechanical and dynamic loads. Natural rubber is not stable versus non-polar liquids such as mineral oils, lubricants, fuels and aliphatic and aromatic and hydrocarbons and chlorides. Its moderate ozone stability can be improved with additives. OZONE RESISTANCE This characteristic is important...
