Clamp for sliding abrasion test

Abstract

The invention discloses a clamp for a sliding abrasion test. The clamp is especially suitable for stably clamping two workpieces for the test through a first clamping assembly and a second clamping assembly under the high-temperature and high-pressure water or steam environment, left horizontal, even and stable pressing force and right horizontal, even and stable pressing force which are the same in magnitude are provided for the two workpieces through a pressing assembly, a friction coefficient and an abrasion coefficient between a tube and a plate are quantitatively measured, loading control and measuring are stable, and operation is easy and convenient. The clamp is reasonable in structural design and functional design. The clamp can effectively control an infinitesimal displacement amplitude between the two workpieces in the testing process, guarantee even and stable loading under the high-temperature and high-pressure water or steam environment for a long time and meet the requirement for time of the abrasion test. The clamp is minimal in size, the volume in an autoclave is reduced, the equipment manufacturing cost and the running cost are reduced, and the problem of measurement of the friction coefficient and the abrasion coefficient of the fretting abrasion test under the high-temperature and high-pressure water or steam environment is solved.

Description

technical field [0001] The invention relates to a jig for sliding wear test, in particular to a jig for sliding wear test suitable for high temperature and high pressure water or steam environment. Background technique [0002] In engineering practice, the problem of component wear and failure caused by vibration often occurs, especially in the nuclear power plant system, some structural parts collide with adjacent structural parts under the action of flow-induced vibration, resulting in friction and wear problems with small displacement amplitudes. At present, experimental research is relatively difficult, and friction coefficient and wear coefficient are difficult to measure. This is mainly due to technical difficulties in the design of fretting wear testers in high temperature and high pressure water or steam environments and fixtures for wear tests in autoclaves. [0003] For fixtures used in autoclave wear tests, the main technical issues include: [0004] (1) The m...
