Исследования гидродинамических характеристик импульсно-волнового воздействия для различных технологических режимов электроразрядных установок разрушения неметаллических материалов

Abstract

A method for the calculation of high voltage discharge channel parameters pressure, radius, and expansion velocity for electric discharge units for destruction of non-metallic materials is presented. It allowed to investi-gate the influence of installation parameters inductance, voltage and capacitance on the hydrodynamic parameters of the discharge channel and generated pressure wave. It is noted that increasing inductivity results in decreasing pressure and expanding discharge channel rate, increasing voltage results in increasing active characteristics of the discharge channel, and increasing capacitance results in increasing discharge current, while pressure and expanding discharge channel rate remaining practically unchanged. The effective area of destruction which depends on the parameters of the technological modes of the cycles, strength properties of the destructible material and electrical conductivity of the discharge medium were determined. The recommendations for selecting operating modes of electrodischarge installations for disintegration of non-metallic materials have been given.

Представлен метод расчета параметров высоковольтного канала разряда давления, радиуса, скорости расширения для электроразрядных установок разрушения неметаллических материалов, что позволило исследовать влияние параметров индуктивности, напряжения и емкости на гидродинамические параметры канала разряда и генерируемой волны давления. При увеличении индуктивности происходит уменьшение давления и скорости расширения канала разряда, рост напряжения, что приводит к расширению активных характеристик канала разряда, а увеличение емкости ndash; к повышению тока разряда, и без изменений остаются давление и скорость расширения канала разряда. Определена эффективная зона разрушения, которая зависит от параметров технологических режимов работы циклов, прочностных харак-теристик разрушаемого материала и электропроводности разрядной среды. Предложены рекомендации по выбору режимов электроразрядных установок для дезинтеграции неметалли-ческих материалов.
