摘要: Simulation and analytical models for the ultrasonic/sonic drill/corer (USDC) are described in this paper. The USDC was developed as a tool in-situ rock sampling analysis support of NASA planetary exploration program. uses novel drive mechanism, which transfers ultrasonic vibrations piezoelectric actuator into larger oscillations free-flying mass (free-mass). free-mass impact on drill bit creates stress pulse at tip/rock interface causing fracture rock. main parts device (transducer, free-mass, bit, rock) interactions between them were analyzed numerically modeled to explore mechanism. Each these is normally by time-dependent 2- or 3-D model involving slowly converging solutions, makes conventional approach unsuitable optimization studies. A simplified integrated using tabulated data simulate operation desktop PC successfully predicted characteristics under variety conditions. simulated results experimental used verify presented.
