Embodiment 1

[0056] The experimental method of the present invention is as follows.

[0057] (1) First, process the tested explosive into a wedge shape to obtain a wedge-shaped explosive. The wedge angle of the wedge-shaped explosive is generally selected to be 15° to 30°. At the same time, according to the impact to detonation distance of the tested explosive and the wedge angle, the length of the bottom edge of the tested explosive is determined, usually 40-60 mm; 40mm; at the same time, process the matching LiF window according to the size of the wedge-shaped explosive.

[0058] figure 1 is the front view of the tested wedge-shaped explosive, figure 2 A side view of the tested wedge-shaped explosive. image 3 is the top view of the LiF window, Figure 4 It is the front view of the LiF window; the length of the bottom edge is determined according to the size of the tested wedge-shaped explosive, and the width is generally selected as 10-20mm.

[0059] (2) According to the test cond...

Abstract

The invention discloses a device for studying the shock initiation performance of an explosive and an experiment method of the device. The device and the experiment method aim at solving the problems that in an explosive shock initiation experiment, both the thickness and the installation gap of a manganin gauge and an electromagnetic particle velocity gauge affect test precision, the test precision of the manganin gauge is seriously affected by the environment temperature, the application cost of the electromagnetic particle velocity gauge is high, and a small amount of data information is obtained by a high-speed scanning camera and can not reflect the state of a post-wave flow field. The device comprises a supporting frame, a transparent measurement window, an optical fiber probe frame and optical fiber probes. The supporting frame comprises a wedge-shaped explosive fixing frame and a fixing device. The wedge-shaped explosive fixing frame comprises a vertical connecting plate and an inclined connecting plate, the included angle between the inclined connecting plate and the horizontal plane is 15-30 degrees, and the inclined connecting plate is provided with a first window. According to the device and the experiment method, high-density and multi-point post-wave particle velocity profiles can be obtained in one experiment, and thus data support is provided for studying the shock initiation performance and detonation performance of the explosive.

Description

technical field [0001] The invention relates to the field of explosives, especially the field of explosive impact testing, in particular to a device for studying the impact initiation performance of explosives and an experimental method thereof. Background technique [0002] Explosives are an important part of the warhead, and the impact initiation performance of explosives has always been a research topic of great concern in the field of detonation. The research object of explosive shock detonation is the process that the shock wave propagating in the explosive develops gradually and transforms into a detonation wave. Moreover, during the production, processing, storage, transportation and use of explosives, the misdetonation that occurs is closely related to the impact initiation of explosives. Therefore, the study of the impact initiation process of explosives is of great significance for the study of its initiation mechanism and safety performance, and has important pra...
