To optimize and improve the impact performance of a hydraulic rock drill, it is helpful to test the stress waves of the drill and analyze the impact energy, impact frequency, and energy utilization rate. For this study, a stress wave test bench was designed and built, according to international. .
Percussion drilling is believed to be an efficient way to enhance the drilling performance, compared with the conventional drilling in deep wells, which could be achieved by applying impact loads above the drill bit. The finite simulation is an efficient method to predict the drilling performance.
