Linear, high speed oscillatory tribometer
SOOG test rig is used for testing wear of flat specimen made of various materials in dry friction. The In standard arrangement there are two fixed specimen of the tested material pressed against the counter-specimen made of stainless steel. The specimen relative sliding motion is a high frequency, low amplitude linear oscillation.
