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 (), a clamping apparatus () arranged on the top of the vertical machine frame () and used for vertically clamping the top end of a sample (), where the sample () is provided at the bottom end thereof with a tray (), a drop-hammering apparatus () used for being dropped vertically from the vertical machine frame () at a set height to impact the tray (), a lifting apparatus used for lifting the drop-hammering apparatus at the bottom of the vertical machine frame () 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. The real-time impact on the tray () when the drop-hammering apparatus is dropped vertically is sensed by a force sensor, while real-time impact data received from a sensor device is analyzed, and a test result is outputted. The dynamics performance testing system is provided with versatility while the test result is accurate and reliable.
