Isolation of mechanical vibrations and solid-borne noise:
To select the correct anti-vibration spring elements it is essential to determine first what events occur in the particular
case:
●
●
●
forced vibrations caused by changing cyclic forces and impulses
impact-like disturbances (shocks) caused by pulses or earth movements
solid-borne noise caused by any sound-waves propagated in solid bodies.
Mechanical vibrations:
The principle of vibration isolation is the separation of the interfering object (active suppression of vibration) or the
object that is to be protected (passive protection of vibration) from the surroundings and, by fitting intermediate springs,
making it into an independent system which is capable of vibrating.
The mechanism of the suppression consists in coordinating the frequency in such a manner that the cyclic movements of
the system are no longer synchronous but in anti-phase to the disturbance.
In case an exciter force directed downwards reaches its maximum, the vibrating object will be in its uppermost position
which means that it moves against the exciting force. Effective vibration isolation will thus be achieved by high
frequency ratio λ .
Flexible mounting design must in principle use natural frequencies, which are outside the resonance field. Unpleasant
rocking must be expected to occur wherever the exciter frequency nerr and the natural frequency ne coincide.
λ < 1 No vibration isolation
Structure-borne noise suppression possible
λ = 1 Rocking × maximum figures depending on damping D
within the resonance area
λ > √ 2 Vibration isolation; efficiency η dependent on λ
structure-borne noise suppression possible
Therefore, effective vibration isolation is achieved by deep frequency tuning, that is, by a high frequency ratio λ . A high
damping effect D is obstructive here because it reduces the isolating effect. However, some degree of damping is
desirable to reduce rocking in the resonance area or to cause rapid amplitudes in case of shocks.
Now, if the object which is to be isolated is artificially separated from the base, the natural frequency of the flexible
mounting must be adjusted to the values which are lower than the exciter frequency by the factor √2.
This frequency ratio λ causes the inertia force of the flexibly mounted system to counteract the exciting force out of
phase. The isolating effect thus introduced is referred to as the isolating efficiency η.
Important Relationships
The magnitudes x, x and x are time-dependent and designate the coordinate, the speed and the mass acceleration m.
Each point stands for one time derivation, known from linguistic usage in mathematics.
Other important definitions in vibration technique:
If the exciter revolution nerr [min-1] is known, divide by ne to obtain the frequency ratio λ .
Spring stiffness of linear springs can be represented by means of the static compression Xst and the weight force G. The
following applies if the spring rate is independent of the frequency: c =
G/xst = mg/xst.
Therefore, it follows from ω2e = c/m, for the natural circuit frequency: ω2e = g/Xst By inserting g = 981 cm/s2 for earth
acceleration, we have:
Damping:
With the x-co-efficient for the movement equation, damping D can be specified non-dimensionally:
However, it can also be obtained from measurements or roughly calculated from the flexibility of materials in accordance
with DIN 53512:
D = (100 – flexibility [%])/950
Solving the movement equation:
The statement X = Xp = A sin (ωt – ϕ ) represents a specific solution of the vibration equation. It becomes an overall
solution when the „transient response" is completed and the system merely vibrates at the exciter frequency ω. The
vibration amplitude is then
V is non-dimensional and is designated as the magnifying function. Its magnitude mainly depends on the frequency ratio
λ.
The relevant phase shift ϕ (lag angle of vibrations in relation to the excitation) can be calculated from the following
relationship:
Vibration isolation:
The ratio of the vibration amplitude to the quotient from P and c is a measure of the „transmittance" of the excitation and,
according to the above formula, equal to the magnification function V. Therefore, the figure of the vibration amplitude A
is equal to the static compression under the constant exciter force amplitude multiplied by the magnification ratio V.
It will now be logical to introduce to it the isolation degree η as a differential amount to 100%.
η = [1 – V] • 100%
For negligible damping,
Structure-borne sound-waves:
These include all sound-waves which are propagated through solids.
Shakings/Vibrations: These are low-frequency structure-borne vibrations
(<50 Hz), such as those created by vehicles, during
building work or by earthquakes.
Footstep noise:
This type of structure-borne noise is generated for example
When walking on stairs, platforms, or floors.
While the isolation of the disturbing forces can be calculated by means of the vibration theory, the damping of structureborne noise comes under the laws of wave mechanics and depends on a variety of parameters. Noise damping is quoted
in decibels (dB) because the effect depends on the sound-reflecting quality (reflection) of the colliding materials.
Sound-hardness:
Sound-hardness of:
Sound-hardness is the product of the sonic
speed and density
Steel = 3.95 × 107 kg/sqm.sec
Cork = 1.18 × 105 kg/sqm.sec
Rubber = 6.62 × 104 kg/sqm.sec
Air = 4.45 × 102 kg/sqm.sec

Technical Info
The softest material as far as sound-reflection is concerned, is air, followed by soft, flexible rubbers.
Rubber-to-metal bonded elements are therefore excellent combinations of acoustically hard and soft materials. Carefully
selected materials of suitable quality (density, Young’s modulus) and thickness create a highly efficient damping effect
over the whole frequency range, by means of the sound reflection losses.

The required compression of 8,4 mm will be found in the above nomogram.
Mounting elements are required to give an 8,4 mm compression at 200 kp.
The effect of damping:
Vibration isolation has nothing to do with vibration damping, as it is erroneously assumed. Effective isolation is achieved
by appropriate frequency tuning alone.
Provisions for damping are required wherever resonance may occur or vibrations from impacts must rapidly decay.
Rocking Ratio
It is evident from the results of experiments that the rubber damping is essentially different from the viscose damping.
Within the frequency area of 10 to 200 Hz the shape force/stroke characteristics (damping ellipses) is constant and
independent of the excitation frequency. The amplitude of the damping force is proportional to the amplitude of the
return force of rubber springs, the proportionality factor representing a material constant independent of the frequency.
The damping factor itself is freuency-dependent in the case of rubber and tends towards zero at a rising frequency.
This means that in the case of small movements the damping forces of rubber are negligibly small and hardly affect the
isolation effect.
On the other hand, the damping effect increases in the case of viscose damping and increasing frequency which is leading
to a deterioration of the isolation effect.
Bonded rubber elements:
Rubber springs are unique anti-vibration elements regarding their vibration and sound damping action. GMT’s
vulcanized materials have proved their efficiency in conditions where elements of other type fail after a short time.
Carefully vulcanized the adherence strength between the metal plate and the rubber may be 130 kp/sq.cm. GMT is now
able to bond various fittings to rubber, such as:
●
●

Steel, crude or treated
Steel, stainless
Brass, aluminium
Plastics
Static stresses on rubber elements:
Compression
The shape factor must be taken into account when designing rubber elements for compression loads. The shape factor is
understood to be the ratio of the action compression area to the open deflection face of the rubber. This is due to the
restricted transverse expansion and thus the variable modulus of elasticity Ec of the incompressible rubber material.
Shearing loads
The shearing modulus G represents the only material constant of rubber and is specified for each compound in relation to
Shore hardness. Therefore, the spring characteristic is linear with parallel shearing stresses. This effect must be
accounted for specifically if there are shearing deformations at higher precompression.
Compression shearing loads:
Anti-vibration elements are often mounted at angles. A bridging connection between them adds stabiblity to such a
flexible mounting together with a corresponding softness in the vertical direction.
Tension
In case the rubber-to-metal elements are subjected to tensions only, peak stresses occur at the edges of the bond. If parts
are oxidized, their serviceability may be destroyed due to the notch sensetivity of rubber. Therefore, tensile stresses
should be avoided.
Dynamic stresses on rubber elements:
The law of non-linear compression of rubber operates only conditionally in the case of dynamic stresses and vibrations
but quite extensively in situations where a large amount of energy must be absorbed.
Our specialists will be pleased to help you in solving complex problems relating to dynamic loads. Any specific figures
which are required can also be measured or checked in our own laboratories.
The values for the modulus G and the corrected modulus of elasticity Ec for simpler static conditions will be found in the
diagrams below.
Hardness:
The hardness of rubber is normally measured in accordance with DIN 53 505 and is expressed in Shore A (C and D). It is
determined by measuring the resistance to penetration of a cone penetrator.
