Material testing machine

Abstract

Provided is a tensile testing machine that includes a testing machine main body having a hydraulic actuator, the tensile testing machine including an estimation unit that estimates a response characteristic of the tensile testing machine, in which the estimation unit obtains the response characteristic of the testing machine main body in a state in which a first set value used for a tensile test performed by the tensile testing machine is set as a control parameter specifying operation of the hydraulic actuator, and estimates, based on the obtained response characteristic of the testing machine main body, the response characteristic of the tensile testing machine in a state in which a second set value different from the first set value is set as the control parameter.

Dependencies are inferred from the claim text.
