Zusammenfassung:PROBLEM TO BE SOLVED: To easily and adequately acquire information by which a tensile force applied to a test object can be specified and a displacement amount of the test object when the tensile force is applied.SOLUTION: In a test system 1, a jack device 10 includes: a piston rod 12 which moves in a predetermined direction in response to the pressure of a hydraulic oil and can apply a tensile force to a lock bottle L; and a stroke sensor 17 which receives supply of electricity and outputs displacement amount information of the piston rod 12. A hydraulic pump device 20 includes: a battery 23; a hydraulic pump 24 capable of supplying a hydraulic oil to the jack device 10; a DC-DC converter 26 and a cable 31 capable of supplying the electricity of the battery 23 to the stroke sensor 17; a pressure sensor 29 for detecting a pressure value of the supplied hydraulic oil; and a USB board 25 capable of inputting the displacement amount information from the stroke sensor 17, associating the displacement amount based on the displacement amount information and the pressure value with each other and outputting the associated displacement amount and the pressure value to the outside.SELECTED DRAWING: Figure 1 【課題】試験対象物に付与した引張力を特定可能な情報と、引張力を付与した際の試験対象物の変位量とを容易且つ適切に取得できるようにする。【解決手段】試験システム1において、ジャッキ装置10は、作動油の圧力に応じて所定方向に移動して、ロックボルトLに引張力を付与可能なピストンロッド12と、電力供給を受けて、ピストンロッド12の変位量情報を出力するストロークセンサ17と、を備え、油圧ポンプ装置20は、バッテリ23と、作動油をジャッキ装置10に供給可能な油圧ポンプ24と、バッテリ23の電力をストロークセンサ17に供給可能なDC−DC変換器26及びケーブル31と、供給される作動油の圧力値を検出する圧力センサ29と、ストロークセンサ17からの変位量情報を入力し、変位量情報に基づく変位量と、圧力値とを対応付けて、外部に出力可能なUSBボード25と、を備えるようにする。【選択図】図1
