Abstract

The invention discloses a high-frequency reciprocating fretting friction and wear tester, which is mainly used for fretting friction and wear tests. The high-frequency reciprocating fretting friction and wear tester comprises a reciprocating drive mechanism, a testing force loading mechanism, a sample clamping mechanism, a signal acquisition and processing system and an electrical control system,and is characterized in that: a testing force loading mode of the testing force loading mechanism is a magnetic loading mode. By the magnetic loading mode, the requirement for loading a small load ismet, and the tester can achieve higher testing accuracy.

Description

technical field [0001] The invention relates to a high-frequency reciprocating friction and wear tester, which is a high-frequency reciprocating fretting friction and wear tester mainly used for fretting wear experiments. Background technique [0002] Wear is one of the forms of material damage and failure. In vibrating machinery, threaded connections, spline connections, and interference fit connections are prone to fretting wear. The mechanism of fretting wear is: the positive pressure between the friction surfaces makes the asperities on the surfaces adhere. Fretting wear can lead to material damage and failure. [0003] At present, in the research of new materials and new processes, in addition to the traditional testing of mechanical, physical and chemical indicators, the testing of friction and wear properties has gradually been widely used. [0004] High-frequency reciprocating friction and wear testing machine is an experimental instrument used to study the frictio...
