Problems solved by technology

When using this type of instrument for metal wire fretting wear test, it is necessary to design additional supporting wire fixtures, and the contact position of the metal wire cannot be guaranteed to be accurate and controllable, so it cannot meet the metal wire fretting wear test
At the same time, the existing wire fretting wear test device cannot realize the precise controllability of the wire test angle, and cannot have both fretting wear and fatigue test functions

Abstract

The invention relates to a metal rubber metal wire fretting wear and fatigue test device and a test method thereof.The metal rubber metal wire fretting wear and fatigue test device comprises a base, a clamp mounting table is arranged on the base, and a micro-amplitude vibration plate is arranged beside the clamp mounting table; a first metal wire clamp and a second metal wire clamp or two first metal wire clamps which are oppositely arranged front and back are mounted on the clamp mounting table; fatigue connecting blocks are arranged on the left side and the right side of the clamp installation table, fatigue metal wire locking mechanisms are arranged on the fatigue connecting blocks, one fatigue connecting block is detachably connected to the base, and the other fatigue connecting block is detachably connected to the micro-amplitude vibration plate. And the second metal wire clamp is provided with a fretting wear connecting seat which is detachably connected with the micro-amplitude vibration plate. The whole device adopts a horizontal arrangement structure, is convenient to use and high in practicability, has fretting fatigue and fretting wear test functions, and can meet the fretting wear and fatigue test requirements of various metal wires, and the fretting fatigue module and the fretting wear module can be replaced with each other.

Description

technical field [0001] The invention relates to the technical field of friction and wear experiments, in particular to a metal rubber wire fretting wear and fatigue test device and a test method thereof. Background technique [0002] The wire inside the metal rubber is a material that combines strength and toughness. During the working process of such materials, fretting friction and wear occurs between the internal wires, resulting in material fatigue failure. Therefore, it is of great significance to study the friction and wear characteristics between various metal wires to improve the fatigue life of metal-rubber materials. . [0003] The reciprocating friction modules of the existing UMT, SRV and other fretting friction and wear testing machines are designed for ball and disk friction pairs, and have lower requirements on the friction position on the surface of the test material. When using this type of instrument for the fretting wear test of the metal wire, it is nec...
