Squeak noises within critical material combinations are no longer a rarity. Due to the continuous individualization of materials and the increasing technical requirements, it becomes more difficult to meet material specifications.
The SSP-04 was developed specifically for the measurement of stick-slip phenomena. This includes the measurement of friction coefficients under conditions of typical application and measurements in the wider climate range from -30°C to +80°C.
Rubbing noises can have a very unpleasant psychoacoustic effect on humans, which can directly causes a negative sensation on the perceived quality of cloths or the touched object. Rubbing noises can additionally cause complete functional failures. Contact partners are for example skin to textile, textile to textile, skin or textile to other materials.
Abrasion and Wear can have a significant influence on materials over its lifetime. This can cause the loss of functionality and therefore be a security risk. With this is in mind OEM´s and their customers are more and more concerned about the compatibility of material combinations. In order to predict the behavior of a material…
Target of the overall project is the consistent application of functional optimized lightweight constructions, to reduce the net weight significantly. The innovative test system features a reduction of the overall net weight, increase of the useable amplitude range and the implementation of the test under climatic conditions of -30°C up to 80°C.
Noise is generated when 2 materials move vertically or tangentially to each other. In many cases, vertical movement results in a rattling noise, while tangential movements result in creaking noises due to material incompatibility. Both can also lead to material fatigue after a longer period of time.
The latest SAREX Shaker meets the NR25 Noise Rating Curve without the need for any enclosure or additional insulation for common S&R vibration profiles. ZINS is thus setting new standards for S&R shakers and is the undisputed technology leader.
