Originally, the device was mainly used to study the friction wear that occurs as a result of vibrations of very small amplitude and high frequency. <\/p>\n

Today, the instrument standardized in DIN 51 834 is frequently used for basic characterization of oils and greases (EP and AW behavior). In addition, it is also used to simulate longer oscillating sliding motions, such as in the piston\/cylinder pairing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

In the model test, a transverse steel cylindrical roller, a steel ring standing vertically on it or a steel ball is oscillated against a fixed steel plate on the face. Lubricating oils, greases, pastes, dispersions and dry lubricating films can be run at various loads in continuous operation or until the lubricating film breaks down. The purpose is to determine the effect, load capacity and service life of lubricants and their additives during oscillating movements. Another field of application is the investigation of materials and surface layers. This can be done dry or lubricated.<\/td>\n<\/tr>\n
The advantage is that only very small quantities of lubricant are required for the tests on the SRV tribometer, the load can be adjusted in a variety of ways and numerous measured variables can be recorded with high precision.<\/td>\n<\/tr>\n
The equipment available at KTM also allows complex dynamic test programs to be carried out. In addition, spatially and temporally resolved stroke and friction signal analysis is possible using the FSA module or High Resolution Signal Analysis (HRA). <\/td>\n<\/tr>\n
Contact resistance and accoustic emission measurements are also possible on individual devices.<\/td>\n<\/tr>\n
