FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, in particular to devices for testing surfaces of parts for abrasive wear, and can be used for testing materials and workpieces. Proposed machine comprises frame accommodating tank with abrasive mix, rotary mechanism coupled with gearbox via coupling, and counter and rotor arranged at transmission output shaft. Test specimens immersed in abrasive mix are fixed on rotor cylindrical surface. Note here that container with abrasive medium can move in vertical plane. Besides, vibration exciter, force and vibration sensors are installed on rotor end part.
EFFECT: technical result is high degree of approximation of test conditions of samples to real operating conditions by creating real dynamic interactions between test samples and abrasive medium.
