Abstract
Disclosed is a device for testing corrosion fatigue resistance on the basis of acoustic emission. The device includes: a main machine including a supporting frame and a tensile mechanism arranged on the supporting frame; a clamping mechanism including a first clamp and a second clamp that is arranged opposite the first clamp, where the first clamp and the second clamp are both connected to the tensile mechanism, the tensile mechanism is used for driving the first clamp and the second clamp to move close to or away from each other, the first clamp is provided with an accommodation cavity for accommodating a corrosive substance, the accommodation cavity is provided with an opening that is provided on the first clamp and close to one end of the second clamp, and the first clamp can place a test specimen in the accommodation cavity when fixing the test specimen.
