Abstract: A dynamics performance testing system, for use in testing the dynamics performance of an anchor rod or an anchor rode, comprising a main machine and a measurement and control system. The main machine comprises a vertical machine frame (1), a clamping apparatus (3) arranged on the top of the vertical machine frame (1) and used for vertically clamping the top end of a sample (6), where the sample (6) is provided at the bottom end thereof with a tray (61), a drop-hammering apparatus (2) used for being dropped vertically from the vertical machine frame (1) at a set height to impact the tray (61), a lifting apparatus used for lifting the drop-hammering apparatus at the bottom of the vertical machine frame (1) to the set height, and a protection apparatus used for physical protection and isolation to reduce bodily injury and noise. The measurement and control system controls the drop-hammering apparatus to select a parameter for drop-hammering and a process of lifting and dropping.

Abstract: A tension meter of an anchor rod with constant resistance and large deformation comprises a pull rod and a hollow jack. The meter further includes: a rotation device for controlling the rotation angle of the hollow jack; a lifter for adjusting the height of the hollow jack and the rotation device; a first hydraulic pump for driving the hollow jack, wherein the hollow jack is fixed on the rotation device mounted on the lifter. The meter has a large measurement range and a high load capacity.
