摘要：

Control of the impact energy delivered to the bit of a percussive rock drill is determined by the piston impact velocity and the piston geometry. The basic equations describing generation, transmission, and reflection of the stress wave are defined and a computer program is described by means of which pistons may be designed to produce waveforms of desired characteristics. © 1968.
