Abstract

The invention discloses a reciprocating type micro-friction abrasion testing machine and belongs to a micro-friction and abrasion testing device. The testing machine comprises a bottom plate, and a bracket, a driving device, a loading device, a positioning and clamping device and a signal conditioning and data acquisition device which are arranged on the bottom plate, wherein the bracket at least consists of two side plates which are longitudinally fixed on the bottom plate; a lower sliding rail seat and a top cylinder seat are at least arranged between the two side plates. An exciter serves as a power source, the equipment is small in size and has high driving force and wide amplitude and frequency variation range, the signal is provided by a signal generation card, multiple driving signals are provided, the frequency and the amplitude are convenient to adjust, and the testing machine is easily controlled by a computer program; meanwhile, a clamp system for a fixation test is simple in structure, reliable in clamping and convenient to mount, and tests in multiple friction pair contact forms can be realized by replacing the clamp. The designed testing machine is high in precision and convenient to operate and provides a reliable experimental instrument for research of micro abrasion.

Description

[0001] technical field [0002] The invention relates to a fretting friction and wear testing device, more specifically, the invention mainly relates to a reciprocating fretting friction and wear testing machine. [0003] Background technique [0004] Fretting wear is a kind of damage that occurs in matching mechanical parts with extremely small amplitude motion. Because the amplitude of motion is very small, it is not easy to be detected, and its damage is concealed. It can not only cause friction and wear between contact surfaces, but also cause damage. Accelerate the generation and expansion of cracks, and finally make the fatigue life of components greatly reduced. Fretting wear can be divided into four modes according to different relative motion directions: 1) tangential fretting; 2) radial fretting; 3) rolling fretting; 4) torsional fretting. Among them, tangential fretting is the most commonly studied fretting method. Although the latter three frequently appear in ...
