Problems solved by technology

For a small laboratory, two testing machines will inevitably increase its cost and space
Finally, the displacement obtained by the universal testing machine is generally the displacement of the crosshead, and the rigidity of the machine has a great influence on the accuracy of the results, which also leads to the fact that the final data obtained by various laboratories cannot be compared horizontally even for the same material and analysis
The inability to share data will also lead to slow application of small punch test technology and continuous indentation test technology in engineering

Abstract

The invention discloses a small-punch and continuous indentation integrated tester system. The small-punch and continuous indentation integrated tester system comprises a computer control system, a small-punch test system and a continuous indentation test system, wherein the computer control system is connected with the small-punch test system and the continuous indentation test system. The small-punch test system comprises a first supporting platform, a fixture, a centering module, a press rod, a first extensometer, a small-punch test bed load sensor and a small-punch test bed extensometer, wherein the fixture is used for fixing a test sample and the press rod, and the press rod is connected with the small-punch test bed load sensor and used for applying load on the test sample. The continuous indentation test system comprises a second supporting platform, a continuous indentation press head clamping rod, a continuous indentation test bed load sensor and a continuous indentation test bed extensometer, wherein the continuous indentation press head clamping rod is used for clamping a press head, is connected with the continuous indentation test bed load sensor and applies load on the test sample through the press head. The small-punch and continuous indentation integrated tester system has the advantages of higher precision, compact product structure, small occupied space and simplicity and convenience in operation.

Description

Technical field [0001] The invention belongs to the technical field of testing machines, and relates to a testing machine system, in particular to a small punch continuous indentation integrated testing machine system. Background technique [0002] Many equipment in nuclear power, petrochemical, metallurgy and other industries have been in service for a long time under harsh environments such as high temperature, high pressure, and strong corrosion, and their materials will deteriorate to varying degrees, and even cause many safety accidents. In order to ensure the long-term and safe operation of the equipment, the pressure-bearing equipment needs to be inspected regularly during service. Conventional non-destructive testing can detect internal or surface defects without damaging the structural integrity of the equipment or components, but cannot obtain the mechanical properties of the material such as yield strength, tensile strength and fracture toughness. For conventional ten...
