Research on static force calibration technology of fatigue test system

The fatigue test system is the main equipment to load performance of anchorage, but for a long time, due lack calibration basis and effective traceability way, it unable calibrate equipment. This paper analyzes structure working principle system, determines its measurement technical indicators requirements through investigation verification. method static force value studied verified by experiments. uncertainty results evaluated, technology with better than 0.50% formed, which lays good foundation this kind
