THE SOLUTION All machinery which by virtue of its design, has reciprocating or rotating parts, creates vibration to some degree through the 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. FFT analysis of orders for a diesel engine For over 45 years, AMC MECANOCAUCHO® has been developing the AMC MECANOCAUCHO ® range of rubber-metal anti-vibration...

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...

Tension tests by non linear FEM 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.

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 ® 4V-SR 3200 ED 45º TRANSVERSAL TEST 100000 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

GENERAL CATALOGUE THEORY OF VIBRATION ISOLATION 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 dampening factor “C”. The frequency of the mass spring system is equal to: The damping parameters are: Where Cc is the critical damping and For this system we obtain a transmissibility T and a magnification factor A: 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 floor. It is defined...

STATIC AND DYNAMIC STIFFNESS 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. All elastomers suffer dynamic stiffening but metallic springs have a very low dynamic stiffening due to the low internal friction of the metals.Therefore we can consider that the springs have identical...

THEORY OF VIBRATION ISOLATION 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. 2.- ANALYSIS OF SYSTEMS OF MORE THAT ONE DEGREE OF FREEDOM In actual fact, there...

• The SYLOMER® mat that these dampers incorporate, isolates the mid-high frequency vibrations which are transmitted through the coils of metal springs. • These high and mid-range frequencies, if they are not isolated, are spread throughout the buildings or structures, generating noise. With the aim to confirm the advantages of applying Sylomer® on our spring system, an analysis of FFT was carried out on fan system of a known international make. The objective of this test is to compare the isolation which the Vibrabsorber springs offer with or without Sylomer®. MEASURES USED • Measuring equipment:...

The spectrums shown in the graphics demonstrate that they are within a frequency range of 0-1000Hz and 1600 lines, represent the vibratory speed. 1. Results on the Machine POINT 1: The maximum vibration rms velocity is situated at 25Hz followed by another of lower magnitude at around 50 Hz. High frequency vibrations are also observed which correspond to harmonics and structural frequency responses from the machine. Results on the Machine POINT...
