摘要
Abstract
A slow cook-off test of RDX based high energy explosives was conducted at a heating rate of 1℃/min by using self-designed cook-off test apparatus.Numerical simulation was performed using FLUENT software.The effects of three kinds of physical interface (air,T-09 and GPS-2 )on slow cook-off characteristics of explosives were researched.The results show that physical interface is an important factor affecting the slow cook-off response characteristics of explosive. Under the same conditions,air as physical interface can increase response temperature,response time and the response severity of the cook-off bomb.Inert material as physical interface can increase the response temperature,the response time of cook-off bomb and reduce the severity of the cook-off response.The numerical calculation results show that cook-off response to temperature and cook-off time are affected by the physical layer thickness of explosive.When the range of the physical layer thickness is 0-5 mm,cook-off response temperature and cook-off time increase with increasing the physical layer thickness.When physical layer thickness increases to 2.5mm,cook-off response temperature and cook-off time reach to maximum,then decrease with increasing the physical layer thickness.关键词
