Application of Standard Impact Specimen in Verification of Instrumented Pendulum Impact Testing Machine

By analyzing the test results of instrumented pendulum impact test method, the applicability of standardimpact specimen in indirect verification of instrumented pendulum impact test machine(Hereinafter referred to as testing machine) is studied. Comparing the characteristic curve of impact process with the absorbed energy of standard sample, the results show that it is more scientific and reasonable to use Charpy V-notch standard sample for indirect verification of instrumented pendulum impact testing machine.
