| description | To provide a material testing machine that is capable of detecting and surely removing an overload applied to a test piece when manually operating an actuator.SOLUTION: A control unit 40 includes: an overload detector 52 which retains a load value that is a criterion for an overload level, and compares a detected value according to a load cell 27 with the overload level, when giving a command signal to a hydraulic actuator 21 via an input part 42, in detecting an overload according to the detected value exceeding the overload level or not; a target value updating part 54 which updates a moving target value of the hydraulic actuator 21, in accordance with the command signal from the input part 42; and an inhibition part 53 which inhibits updating of the target value in a loading direction by the target value updating part 54, when an overload is detected by the overload detector 52.SELECTED DRAWING: Figure 2
【課題】アクチュエータの手動操作時に供試体に加わる過負荷を検出して確実に除荷することができる材料試験機を提供する。【解決手段】制御部４０は、過負荷レベルの判定基準となる荷重値を保持し、入力部４２を介して油圧アクチュエータ２１に指令信号を与えているときに、ロードセル２７による検出値と過負荷レベルを比較し、検出値が過負荷レベルを超えたかどうかにより過負荷を検出する過負荷検出部５２と、入力部４２からの指令信号に応じて、油圧アクチュエータ２１の移動目標値を更新する目標値更新部５４と、過負荷検出部５２が過負荷を検出したときに、目標値更新部５４による目標値の負荷方向への更新を禁止する禁止部５３とを有する。【選択図】図２ |
