Areas of appli­cation SSP-​​04:
    • Evalu­ation of any material combi­nation for potential squeaking noises
    • Measurement of the elastic-​​plastic behaviour of compo­nents (e.g. seals)
    • Simulation of mileage driven for example 100,000 kmcan be simulated to determine the abrasion behaviour of coatings or surfaces.
Areas of appli­cation H3P:
    • Inves­ti­gation of material pairings under the influence of third substances such as oil, grease, dust and lubri­cants.
    • With a specially integrated abrasion mode the change of friction between a material combi­nation can be tested.
    • Measurement of the influence of dust on seals against painted sheet metal or glass.

The occur­rence of stick-​​slip phenomena when using certain materials can be attributed either to incom­patible material combi­na­tions or to the influence of third substances. With the SSP-​​04 and H3P stick-​​slip test stands, ZIEGLER –Instru­ments can predict possible stick-​​slip effects and the associated squeak problems.

The selection of a suitable material or a suitable material combi­nation prevents disturbing noises by stick-​​slip and thus ultimately customer complaints. Due to many years of experience – and numerous research projects – ZIEGLER-​​Instruments has a high degree of special knowledge around the topic of material pairs and the influence of third materials.

We make this knowledge available to our customers as a service by carrying out stick-​​slip tests with our own test stands within our material lab. However, we do not only provide measurement results but also propose solutions based on our expertise to avoid stick-​​slip effects.

Since today’s products should not only be flawless upon delivery, but also after several years, the lifetime plays an increas­ingly important role. For this reason, we have developed a special lifetime profile which allows us to simulate 100,000 driven kilometres on our test stands.

Conclusion

Stick-​​slip measure­ments provide indica­tions of critical material combi­na­tions and the influence of third substances which reduce the objective quality of the product through abrasion and wear. In addition, these effects also reduce the subjective quality of a product due to unwanted noises.

Benefits
  • Shorter devel­opment times
  • Faster product launch
  • Increase of the product quality
  • Avoidance of after works
  • Reduction of warranty costs
