Abstract

The invention discloses abrasive particle shear fatigue test equipment. The abrasive particle impact fatigue test equipment comprises abrasive particles fixedly connected with a tool head, a scratched test piece, a base system, an ultrasonic vibration system, a force measuring system and an acoustic emission system, wherein the ultrasonic vibration system is mounted on and connected with the base system; the tool head is fixedly connected with the ultrasonic vibration system; the acoustic emission system is mounted on and connected with the tool head; the force measuring system is mounted on and connected with the base system; the scratched test piece is fixedly connected with the force measuring system; the relative position between the scratched test piece and the abrasive particles is adjusted through the base system; the shear sliding between the abrasive particles and the scratched test piece is realized by the ultrasonic vibration system; the force measuring system is used for detecting dynamic force change between the abrasive particles and the scratched test piece; the acoustic emission system is used for carrying out acoustic emission of signals when the abrasive particles reach the fatigue rupture condition during the shear sliding process between the abrasive materials and the scratched test piece. The abrasive particle impact fatigue test equipment disclosed by the invention can quantize and compare the shear resistance of different abrasive particle materials, and meanwhile, provides the shear resistance time data, so as to achieve the theoretical guiding significance in the aspects of abrasive material manufacture, abrasive tool design and the like.

Description

technical field [0001] The invention relates to an abrasive particle shear fatigue testing device. Background technique [0002] Abrasive processing is a common processing method to achieve high-level machining accuracy, including grinding, grinding, polishing and other technological forms. In abrasive processing, the contact between abrasive grains and the processed material causes the soft workpiece material to be crushed. In this process, the abrasive grains are inevitably subjected to dynamic loads such as shearing, and wear and tear occur, which in turn affects the performance of the abrasive grain tool. Therefore, the shear resistance of abrasive grains under dynamic loads has a great influence on the performance of abrasive grain tools. But there is no simple and effective method to quantify the shear fatigue characteristics of abrasive particles. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior a...
