Description
Summary:The relevance of the research is caused by the need to develop new sources of powerful current pulses for creation of seismic waves in non-explosive seismic exploration. The aim of the research is to carry out estimated and pilot investigations of operation of inductance-capacitance oscillator model using the generalized laws of switching for receiving current pulses in the resistive load. Objects: laboratory model of the inductance-capacitance oscillator with inductively connected inductance coils for increasing current pulse power and steepness in linear active loading. Methods: method of state-space variables for calculating the equations of transient phenomenon in a circuit after switching which are worked out under Kirchhoff's laws, application of the generalized laws of switching for calculating the starting values of currents in the inductance coils and in load resistance. Results. The authors have designed the diagram of the inductance-capacitance oscillator which uses the generalized laws of switching for receiving power current pulses in the resistive load. The oscillator contains the inductive and connected coils that allow increasing the reserved energy and power of the received pulses. Using the method of state-space variables, the mathematical model of operation of the diagram on the linear resistive load was obtained. The authors performed the estimation and pilot researches of the diagram laboratory model. The experimental values of currents in inductance coils and in loading coincided approximately with the calculated ones. Duration of the received current pulses in loading and steepness of the forward front of current pulses make perspective the application of the inductance-capacitance oscillator in seismic exploration, as a source of seismic waves at explosion of a delay.
