Abstract

Theunderwaterexplosionprocessofmineslyingonseabedwassimulatedbyusingthe meshfreeSPH method.Andthesubstanceinterfacesweretreatedbyadoptingtheimpedancematching method.Thereflectioncoefficientsofthepeakpressuresindifferentdirectionsatdifferentdistances fromtheexplosioncenterwereobtained.Thedistributionandchangeoftheexplosionfieldparameters wereanalyzed.Andtheeffectsofdifferentsandthicknessanddifferentchargemassonshockwave propagationandpressurewerediscussed.Simulationresultsshowthattheseabedreflectioncoefficient varieswiththeanglebetweenmeasuringpointsandhorizontallineanditarrivesatthemaximumvalueof1.5whentheangleisabout55degree. Itishelpfulfordeterminingtheexplosionloadofmines lyingonseabed.
