Test laboratory
and quality assurance

When you need to control vibrations, you want to achieve the best possible result. We believe that we have not done our job properly until your problem with vibrations, shocks and noise is solved.

That is why we rely solely on our own test results. Product and performance data provided by third parties are sometime unreliable. We know this from experience and prefer to verify measurements – for every individual product which we supply.

STS Schwingungstechnik Schuster GmbH has its own test facilities for static and dynamic analysis. The centrepiece is a DYNA-MESS machine which we use for static and dynamic push and pull tests.

With its large operating range from 1 kN (100 kg) to 100 kN (10 t), the machine covers the entire spectrum of vibration dampers. It is precision-calibrated to class 1 in its entire working range.

We will carry out the following tests for you:

Static testing

  • Static damper compression
  • Calculation of the correct installation height of machine feet and
    anti-vibration mountings, e.g. under the effective machine weight
  • Parameters: static stiffness, spring rate

Static load limit testing

  • Increase of load until failure of damper (break …)

Creep testing

  • Endurance test under constant load
  • Calculation of creep properties/subsidence of damper

Dynamic testing

  • Parameters: dynamic stiffness, dynamic spring rate
  • Calculation of natural frequency
  • Change in damping action due to self-heating

Sweep testing

  • Dependency of dynamic spring rate on vibration generator frequency
  • Dependency of dynamic spring rate on vibration generator amplitude
  • Dependency of damping on frequency and amplitude
  • Isolation rate
  • Calculation of isolation rate at known vibration generator frequency

Durability tests

  • Dynamic endurance test at known vibration generator frequency
  • Analysis of dynamic long-term behaviour (e.g. dynamic creep)
  • Assessment of damage symptoms (fatigue, vulcanisation degradation…)

The DYNA-MESS machine is very versatile and can also be used for other special purposes, such as to test combinations of dampers, to reproduce specific conditions in special cases, to carry out tensile tests… .

Not only do the insights gained from our own extensive tests form the basis for our approach to giving professional advice and finding solutions but they are also fundamental to the quality of our products and their long-term stability in heavy-duty industrial applications.

You will find many suppliers who will sell you anti-vibration mountings from a catalogue but STS Schwingungstechnik Schuster GmbH is an authority on the subject on the basis of the following:

And so you have come to the right place if you need a specialist.
