Problems solved by technology

At present, the sensitivity test of penetration testing mostly uses sensitivity test blocks, but the sensitivity test blocks cannot be reused, the cost is high, and the defect size is limited
In the research related to penetrant flaw detection reagents, a workpiece crack simulation device that is easy to obtain, reusable, with adjustable crack parameters and high reliability is needed, so the sensitivity test block alone cannot meet the use requirements

Abstract

The invention relates to a reusable workpiece crack simulation device. Lug plates are respectively arranged on two sides of a base, wherein internal thread holes are formed in the lug plates; the internal thread holes are matched with bolts by threads; metal plates are arranged at end parts of the bolts in the base; a pressure sensor is arranged on the metal plate; only one pressure sensor is provided; a metal block is placed between the pressure sensor and each metal plate; and the metal block is placed on a crack simulation groove inside the base. The reusable workpiece crack simulation device provided by the invention is detachable and reusable, has a pressure characterization function, and is continuously adjustable in crack width.

Description

technical field [0001] The invention relates to the field of penetration detection, in particular to a detachable, reusable workpiece crack simulation device with pressure characterization function and continuously adjustable crack width. Background technique [0002] Penetrant testing (abbreviated as PT), also known as penetrant testing, is a non-destructive testing method based on the principle of capillary action to check surface opening defects. This method is one of the five conventional non-destructive testing methods (ray testing, ultrasonic testing, magnetic particle testing, penetration testing, eddy current testing), and is a comprehensive science and technology. [0003] Like other non-destructive testing methods, penetration testing is based on the premise of not damaging the performance of the tested object, using physics, chemistry, material science and engineering theory as the basis, and effectively testing various engineering materials, parts and products. ...
