- W4323786176 abstract "Ultrasonic drilling for studying the properties of extraterrestrial objects, detecting valuable substances in deep layers of the soil or ensuring the maximum speed of preparation of channels to a certain depth to fix the landing modules requires continuous information about the process of impact with the earth with unknown properties. The presence of such information ensures the optimization of the effect, that is, the maximum energy efficiency of the procedure, subject to obtaining the necessary information about the state and properties of the treated soil. In the process of drilling, the mechanical properties of the soil determine the acoustic load on the emitter due to the relationship between the alternating voltage and current through the piezoelectric transformer of the ultrasonic vibrating system. The electrical parameters of the piezoelectric oscillatory system can be measured directly, and one or more mechanical properties of the soil can be determined automatically from their values. However, this method for determining the properties of a medium has so far been implemented only for liquids prone to cavitation. A model of the interaction of a piezoelectric ultrasound emitter with the ground, taking into account the shock-contact nature of the impact, is proposed and developed in the article. The analysis of the model made it possible to establish the relationship between the mechanical resistance of the soil and its properties. The revealed relationship can be used to determine the properties of previously unknown soil in real time during ultrasonic drilling using devices that guarantee the optimal impact on each soil by determining the properties and content." @default.
