Abstract:The drilling processes of the drill rod of hydraulic revolving-drilling under different surge pressures, rotation pressures and propulsion forces are recorded by a high-speed camera. Meanwhile, the curves of the impact vibration, torsional vibration and frame vibration during the revolving-drilling processes are plotted with the digital picture processing technique. The impact frequency, torsional vibration frequency, torsional vibration amplitude, and vibration amplitude of the drill rod and frame are calculated. The photogrammetry results generally agree with traditional test results. High-speed photogrammetry is a non-contact measurement with wide application and high precision through which the drilling process can be described adequately and visually.
