Description
Technical Field
The application belongs to the technical field of explosive performance parameter experiments, and relates to an explosive accelerating device and method, which are mainly used for explosive impact performance experiments and can provide technical support for the design of overload-resistant explosives and insensitive explosives.
Background
The explosive is a destructive energy source of conventional weapon ammunition, and is widely applied to various penetration ammunitions and shot ammunition, and the ammunition can meet the large overload condition of tens of thousands of gravity accelerations in the using process, so the anti-overload performance of the explosive needs to be fully considered in the design process of the explosive formula. In order to simulate the overload environment of ammunition, researchers establish a large number of explosive acceleration test devices, such as light gas guns, artillery guns, rocket prying and the like, but the test devices can only be used for researching the explosive loading performance of the explosive and cannot be used for testing the explosive bare powder column. However, the impact safety of the explosive itself has important reference significance for comprehensively understanding the explosive and the charging safety thereof, and the rocket prying test can effectively accelerate the explosive bare charge to carry out the test, but has the problem of high test cost (the single test cost is nearly millions); the high-speed moving body accelerating device and the method (publication number: CN 109556820A) for the strong impact test, which are proposed by the West's safety university in 2019, can effectively reduce the occupied area of accelerating equipment, and have the characteristics of high impact speed and high safety, but the method does not consider the characteristic that energetic materials such as explosives are sensitive to external mechanical stimulation, so that the method is not suitable for the energetic materials such as explosives; in order to solve the problem, the current solution is to accelerate the inert substances to impact the bare drug column according to the principle of relative motion, and typical test methods include a STEVEN test (dawn standing waves by antidune and the like, and the research on the explosive response rule under the impact of bullets with different shapes in the Steven test), a Hopkinson bar test (the research on the national defense science Lu Fang Yun team), and the like. In summary, the current testing device is only suitable for explosive charges (explosives with shells), and has the following three limitations:
(1) the single test cost of rocket prying is nearly millions of RMB, the rocket prying is difficult to be used for conventional scientific research, and an explosive accelerated impact test method established according to a relative motion principle cannot completely replace an explosive direct acceleration test method;
(2) at present, a safe and reliable direct acceleration test of the bare explosive column is realized without a method, and the impact dynamic mechanical property of the bare explosive column cannot be directly measured;
(3) the explosive acceleration process is a black box, and the accident reason is difficult to analyze if a chamber explosion event occurs.
The impact dynamic mechanical property of the explosive is one of the core problems of overload-resistant explosive and insensitive explosive design attention, and the existing explosive acceleration test device has certain limitations, so that an explosive acceleration device and method are needed, the explosive acceleration test scheme is enriched, the defects of the existing test device are overcome, and the technical guarantee is provided for better researching the dynamic mechanical property of the explosive.
