Theoretical Approach of Determining Expansion Law of Cylinder under the Detonation Driving of Multi-Component Explosive
摘要
Abstract
In order to provide basic data for quickly predicting JWL (Jones-Wilkins-Lee)parameters of multi-component explosive with any component ratio,this paper presents a theoretical approach for quickly determining the expansion characteristics of cylinder driven by detonation products of multi-component explosive in a cylinder test.Namely,based on the JWL parameters of each component in multi-component explosive,according to energy conservation principle and using Gurney model,the expansion displacement-time curve of cylinder under the detonation driving of multi-component explo-sive can be obtained.Meanwhile,utilizing energy conservation principle and the relationship between detonation velocity,detonation pressure and detonation heat from constantγ equation of state in classi-cal detonation theory,this paper also presents a theoretical approach for determining the detonation velocity and detonation pressure of multi-component explosive with any component ratio.Using this method,the cylinder expansion characteristics,detonation velocity and detonation pressure of a PBXC03 and a PBXC10 multi-component explosive were calculated,respectively.It is found that the calculated results are in good agreement with previous experimental results,which verifies the feasibil-ity of the theoretical approach.关键词
