引張試験機、及び引張試験機の制御方法
Document Type and Number:
Japanese Patent JP7306464
Kind Code:
B2
Abstract:
A test result of a tensile test and a measurement result of a natural frequency are easily associated with each other. A high-speed tensile testing machine 1 is a tensile testing machine that executes a tensile test by applying a test force F to a test target TP. The machine includes: a determination unit 513 that determines a timing at which a striking force FD is applied to a testing machine body 2; a striking structure 60 that applies the striking force FD to the testing machine body 2 at the timing determined by the determination unit 513; a first detection unit 514 that detects a vibration of the testing machine body 2 generated by the striking force FD; a calculation unit 515 that calculates a natural frequency FA of the high-speed tensile testing machine 1 on the basis of a detection result of the first detection unit 514; an execution instruction unit 516 that executes the tensile test; and a recording unit 517 that writes, in a result storage unit 518, information indicating a test result of the tensile test in association with information indicating the natural frequency FA. The timing is included in either before or after the tensile testing machine 1 executes the tensile test.
