According to the energy-delivering model of the drilling steel in super-hard rock, This article adopts ANSYS three dimensions simulation finite element analysis(FEA) software and the methods of the dynamics harmonic analysis, has analyzed the stress state and deformation of the “Flying Dragon” series number ZQ25-2041 integral drilling steel when it bears percussive stress wave. This article has also indicated the dangerous work frequency and gave the theories base for estimating the fatigue life of the drilling steel rod in super-hard rock.
