Vibration isolation for machines

Yes, even machines that are already installed can be reliably vibration-isolated. Presses, automatic punching presses and other heavy production systems in particular generate enormous forces with every stroke, which are transmitted directly into the hall floor and the building structure without being damped. The consequences: Vibrations, disruptive structure-borne noise, possible damage to the building fabric as well as limited accuracy and increased wear on the machine itself.

With isoloc systems, we offer customised solutions that can also be retrofitted - without the need for costly foundation renewal.

Here you can find an example of direct insulation with isoloc HPD500 press bearing systems for a 4,400 kN EUMUCO forging press.

Our experienced measurement engineers carry out precise vibration analyses directly on your premises - using state-of-the-art measurement technology, methods and software. This enables us to record the dynamic behaviour of your machines and/or building structure, relevant vibration variables such as natural frequencies, damping properties and excitation frequencies, as well as acceleration (amax) and velocity (vmax).

The aim of this phase is to precisely identify the causes of the oscillations (e.g. running mechanisms, impact effects), assess their effects - all in accordance with relevant standards and VDI guidelines. After implementing an isoloc solution, we carry out another measurement to evaluate the residual oscillations and document the success of the measure.

Based on the measurement data obtained, our engineers create a customised isolation concept - tailored to your machine and your requirements. Our services include the selection and dimensioning of suitable isoloc products, finite element calculations,modal analyses, dynamic simulations and static calculations for the precise design of the solution.

All isoloc systems are based on experience with high-performance elastomers, which are predestined for resilient Support, ~ mounting of machines. They ensure a low natural frequency, high dimensional stability and minimal creep behaviour. This ensures reliable vibration decoupling. Our solutions also impress with their cost-effectiveness and durability. They are maintenance-free, increase productivity and optimise machine performance.

A vibration-isolated machine foundation is required in the following cases:

1. the machine or system requires installation on a foundation for stiffening. These can be, for example, measuring machines, printing machines or very long turning and drilling machines. For this reason, the elastic vibration isolation elements must be installed under the additional mass (usually a concrete block).

2. if the weight is increased by the additional mass and the bearing natural frequency is therefore lower with the same number of vibration isolation elements due to the higher compressive stress.

3. with the bearing natural frequency remaining the same to reduce the amplitudes of the vibration-isolated machine including the foundation.

4. to reduce the amplitudes (absolute movement) of the elastically mounted machine due to the greater inertial mass. Prerequisite: Overall stiffness of the Vibration insulation remains constant despite greater mass = more Vibration insulation elements. The connected elements are subjected to less stress. Additional stiffening of the machine, lower inertia forces act on the machine components (longer service life).

Vibration isolation refers to measures that are intended to prevent vibrations from being transferred from one System to another. This is usually achieved by means of a separating construction, for example in the form of a spring-mass system. In contrast, dynamic damping aims to reduce the strength of oscillations in an individual System. This involves converting some of the kinematic energy into heat, often through friction. So while isolation blocks the transmission of vibrations, damping reduces the intensity of the oscillations themselves.

Here you will find our FEDAM machine mounting systems for effective damping. FEDAM elements can be used for both source insulation and recipient insulation.
